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:
l = 16 feet
Step-by-step 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
