Question

1.) The length of a rectangle is twice the width. The perimeter is 36 feet. Find the

length and width
Unknowns:
_______= width
_______= length
Write an equation and solve: (Remember that perimeter is 21 + 2w.)
Width=____ length =_______​

Answer 1

12

Explanation:

Answer 2

Width = 6.

Length = 12.

Explanation:

2L + 2W = 36 where W = width and L = the length.

Since L = 2W , substituting:

2*2W + 2W = 36

6W = 36

W = 6

so L = 2*6 = 12.
