It is given in the question that side length = 30 inches.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Therefore, the perimeter of an equilateral triangle will be 3 \u00d7 30 = 90 inches.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Q2. What will be the perimeter and semi perimeter of an equilateral triangle whose side measurement is 10 units?<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Solution<\/strong>:<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">You know the perimeter of an equilateral triangle is 3 times the side length, and the semi-perimeter is half the perimeter.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Put in the values: side length = 10 units.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Therefore, the perimeter of the equilateral triangle will be 3 \u00d7 10 = 30 units and<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">the semi-perimeter of an
