Question

A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to determine the length, in feet of the mat. Then find the area, in square feet, of the mat.

Answer 1

x= width

2x = the length

P = 2(x+2x)

P = 2*3x=6x

36 = 6x

x= 6

the length=6*2=12feet

area:

12*6 =72ft²
