derive the area of a rectangle, we use the unit squares. How to find the area of a rectangle using unit squares?<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">We can find the area of any two-dimensional shape by dividing that shape into smaller unit squares. Since each unit square occupies one square unit space, the total number of unit squares in the shape gives its area. The area of a shape is measured in square units. So, the unit of area of a rectangle is \u2018square units\u2019. Let\u2019s understand how to find the area of a rectangle using unit squares.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Example 1: <\/strong>Divide the rectangle ABCD into unit squares, as shown. The area of a rectangle ABCD is the total number of unit squares contained within it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"174\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/rectangle-formed-using-unit-squares-each-having-1-square-inch-area.png\" alt=\"Rectangle formed using unit squares each having 1 square inch area\" class=\"wp-image-41597\" title=\"Rectangle formed using unit squares each having 1 square inch area\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/rectangle-formed-using-unit-squares-each-having-1-square-inch-area.png 680w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/rectangle-formed-using-unit-squares-each-having-1-square-inch-area-300x77.png 300w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Thus, the total area of the rectangle ABCD is 48 sq. inch.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Also, using this approach, we find that the area of a rectangle is always the product of its two sides. Here, the length of AB is 8 inches and the length of BC is 6 inches. The area of ABCD is the product of 6 and 8, which is equal to 48.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Example 2: <\/strong>Consider a rectangle of length 6 in. and width 3 in. It can be filled with 3 rows and 6 columns of unit squares.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"418\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/finding-the-area-of-a-rectangle-using-the-unit-squares.png\" alt=\"Finding the area of a rectangle using the unit squares\" class=\"wp-image-41598\" title=\"Finding the area of a rectangle using the unit squares\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/finding-the-area-of-a-rectangle-using-the-unit-squares.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/finding-the-area-of-a-rectangle-using-the-unit-squares-300x202.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Each of these squares has an area of 1 square inch, and in the rectangle, there are 18 such squares. So, the area of the rectangle is 18 square inches.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The unit of area of a rectangle is \u201csquare units\u201d (square inches, square feets, etc) as the lengths are multiplied together, so are the units.<\/p>\n\n\n\n<div id=\"recommended-worksheets-container-id\" class=\"recommended-games-container\"><h4
