Question

A rectangular excercise.mat has a perimater of 48 feet. The length of the mat is twice the width. Write and solve an equation to determine the length in feet of the mat.​

Answer 1

l = 16 feet

Explanation:

P = a + b + c + d.

P = 2x + x + 2x + x = 48

6x = 48

x = 48/6

x = 8 feet

Thus, length = 2x = 2(8) = 16 feet
