# Difference between Square and Rectangle – Definition, Examples, FAQs

## What Is the Difference between Square and Rectangle?

Squares and rectangles are quadrilaterals. The major difference between square and rectangle is, all sides of a square are equal, on the other hand, only opposite sides of a rectangle are equal.

Take a look at the shape of a square and a rectangle to get a better idea!

## Definition of Square and Rectangle

A square and a rectangle are both quadrilaterals (or polygons with 4 sides). Let’s understand the definitions.

Definition of Square

A square is a quadrilateral with four equal sides, four vertices, and four interior angles measuring 90°.

A square is a regular polygon since all its sides are equal and all angles are congruent.

A chessboard is the best example of a square shape in daily life. Observe that there are also 64 small squares on a chess board.

Rectangle

A rectangle is a quadrilateral in which the opposite sides are parallel and equal to each other and all four angles measure $90^{\circ}$

The longer side of a rectangle is called length. The shorter side is called breadth.

Some examples of rectangles around us are dollar bills, chalkboard, books, etc.

## What Are the Properties of Squares and Rectangles?

Let’s learn some of the important characteristics of a square and a rectangle. It will help us in identifying the important differences between them.

Properties of a Square

• A square has four sides, four interior angles, and four vertices.
• All sides of a square are equal. (The sides AB, BC, DC and AD are all equal.)
• Each interior angle of a square equals $90^{\circ}$.
• The opposite sides of a square are parallel to each other.
• The diagonals of a square are equal.
• The diagonals of a square bisect each other at $90^{\circ}$.

Properties of a Rectangle

• A rectangle has four sides, four interior angles, and four vertices.
• The opposite sides of a rectangle are equal.
• Opposite sides of a rectangle are parallel to each other.
• All the interior angles in a rectangle measure $90^{\circ}$.
• The diagonals of a rectangle are equal.
• The diagonals of a rectangle bisect each other. They are not perpendicular. They form two angles, one acute and one obtuse.

## Square vs. Rectangle

How are squares and rectangles alike? How do they differ from each other? Let’s compare and contrast squares and rectangles, and find out different similarities and differences.

## Difference between a Square and a Rectangle

Now, we have a good idea about squares and rectangles, their properties, and the basic differences. Let us summarize the difference between square and rectangle based on different properties like sides, diagonals, formulas for area and perimeter, etc.

## Why Is a Square Also a Rectangle?

A square is considered a special kind of rectangle since it satisfies all the properties of a rectangle.

• They both have all interior angles of $90^{\circ}$.
• The opposite sides of both squares and rectangles are equal and parallel.
• The diagonals are equal. Also, diagonals bisect each other.

Thus, all squares are rectangles. However, all rectangles are not square since there are some properties of the square that do not apply to a rectangle.

• All sides of a square are equal.
• The diagonals of a square bisect each other at $90^{\circ}$.

## Facts about Squares and Rectangles

• A cube is a 3D shape. It has 6 faces, all of which are squares.
• A rectangular prism is a 3D shape. It has 6 faces, all of which are rectangles.
• A Square is a regular polygon.
• A rectangle is an irregular polygon.

## Conclusion

In this article, we learned about differences and similarities between a square and a rectangle with the help of the definitions, table. Let’s solve a few examples and practice problems for better understanding.

## Solved Examples on the Difference between Square and Rectangle

1. Find the area of the square with a side of 5 inches.

Solution:

Side $= 5$ inches

Area of square $= side \times side$

Area $= 5 \times 5$

$= 25\; inches^{2}$

2. Find the area and perimeter of a rectangle with length 8 inches and width 6 inches.

Solution:

Length $= 8$ inches

Width $= 6$ inches

Area of rectangle $= length \times width$

Area $= 8 \times 6 = 48\; inches^{2}$

Perimeter of rectangle $= 2 \times (length + width)$

$= 2 \times (8 + 6)$

$= 2 \times 14$

$= 28$ inches

Therefore, the area of the rectangle is $48\; inches^{2}$, and the perimeter of the rectangle is 28 inches.

3. The length of a rectangular field is 10 feet, and the width is 8 feet.

(i) What is the area of the field?

(ii) What will be the total length of the boundary of the given field?

Solution:

Length $= 10$ feet

Width $= 8$ feet

(i) To calculate the cost of painting the field, we need to find the area covered by the field.

Area of rectangle $= length \times width$

Area of field $= 10 \times 8$

$= 80\; feet^{2}$

(ii) Total length of the boundary $=$Perimeter of the field

Perimeter of rectangle $= 2 \times (length + width)$

Perimeter of the field $= 2 \times (10 + 8)$

$= 2 \times 18$

$= 36$ ft

4. Find the total area.

Solution:

The given figure is formed by a square and a rectangle.

We can divide it into a square having side 3 units and a rectangle of dimension 6 units 2 units.

Area of the square $= side \times side = 3 \times 3 = 9$ square units

Area of the rectangle $= length\times breadth = 2 \times 6 = 12$ square units

Total area $= 9 + 12 = 21$ square units

## Practice Problems on Difference between Square and Rectangle

1

### The side of a square is z units in length. What will be the perimeter of the square?

$z + z$ units
4z units
$(z + z + z + z)$ units
Both b and c
CorrectIncorrect
Correct answer is: Both b and c
The formula for the perimeter of a square is 4 side. Also, the perimeter is the sum of all sides.
Therefore, 4z units $= (z + z + z + z)$ units is the perimeter.

### What is the area and perimeter of the given rectangle?

Area $= 70\; \text{inches}^{2}$, perimeter $= 36\; \text{inches}$
Area $= 77\; \text{inches}^{2}$, perimeter $= 34\; \text{inches}$
Area $= 72\; \text{inches}^{2}$, perimeter $= 38\; \text{inches}$
Area $= 77\; \text{inches}^{2}$, perimeter $= 36\; \text{inches}$
CorrectIncorrect
Correct answer is: Area $= 77\; \text{inches}^{2}$, perimeter $= 36\; \text{inches}$
Area of rectangle $= length \times width = 11 \times 7 = 77\; \text{inches}^{2}$
Perimeter of rectangle $= 2 \times (length + width) = 2 \times (11 + 7) = 36$ inches.

### Which of the following statements are not true about both squares and rectangles?

The diagonals are perpendicular bisectors.
The opposite sides are parallel.
The diagonals are equal in length.
CorrectIncorrect
Correct answer is: The diagonals are perpendicular bisectors.
The diagonals of a square bisect at right angles. However, the diagonals of a rectangle only bisect each other. They are not perpendicular.

## Frequently Asked Questions on the Difference between Square and Rectangle
