Answer:

Length = 12 ft

Step-by-step explanation:

Given perimeter of the mat = 36ft

Length of mat = 2 times width

Let the WIDTH be "x"

LENGTH =2 * x ,= 2x

The EQUATION of the perimeter (P) of a rectangle is expressed as:

P = 2 (l + w)

Where l = length = 2x

w = width = x

36 = 2 ( 2x + x )

36 = 2 (3x)

36 = 6x

Divide through by 6

x = 36 / 6

x = 6.

Therefore, width = 6

Length = 2 * w

Length = 2*6

Length = 12ft
