Question

the perimeter of a rectangle equals the sum of of the lengths of its four sides. if the width of a rectangle is 3 inches and its perimeter is 38 inches, find the length of the rectangle. the length of the rectangle is?

Answer 1

16

Answer 2

Let P = perimeter, L = length, W = width
then P = 2L + 2W
Since P = 38 and W = 3,
38 = 2L = 2(3)
Solve the equation for L, and you get the length.
