The perimeter is the length of the outside. If you know the length of one side, multiply that times four to get the perimeter.
To find this answer, use the perimeter formula for a rectangle and plug in the numbers. (l+w)(2) (7.5+7.5)(2) 15(2) 30m
The distance around a figure. For a polygon, add the lengths of all of its sides to get the perimeter.
Since the formula for the perimeter of a rectangle is 2 times the lenght plus 2 times the width (P = 2l + 2w). P = 2(8) + 2(3) P = 16 + 6 P = 22m
