P = 2 L + 2 W
L = 2 W + 8
2W + (4 W + 16) = 64
W = 8

Let
l = length
w = width
P = perimeter
Given
--(1) l = 8 + w
--(2) P = 2l + 2w
--(3) P = 64
Substitute l & P(from 1 and 3) to eq. 2
64 = 2(8 + w) + 2w
distribute
64 = 16 + 2w + 2w
transpose and combine
48 = 4w
use symmetric property
4w = 48
divide by 4
w = 12 inches
therefore, the width is 12 inches!

Use x for width, and 2x for length (for the reason that's two times the size of width) x + x + 2x + 2x = 40 two 6x = 40 two x = 7 so 7 is the width length is 14 examine the respond 7 + 7 + 14 + 14 = 40 two

The width is 8 in, the length is 24in, the perimeter is 2xlenhth + 2xwidth = 2x24 + 2x8 = 48 + 16 = 64

Let width = x
Length = 2x + 8
Perimeter = 2xlength + 2xwidth
so, perimeter = 2(2x+8) + 2x = 64
4x+16 + 2x = 64
16 + 6x = 64
6x = 64 - 16
6x = 48
x = 48/6
x = 8
So, Width = x = 8inches.

l = 2w + 8
64 = 2((2w + 8) + w)
64 = 2(2w + 8 + w)
64 = 2(3w + 8)
32 = 3w + 8
3w = 24
w = 8
l = 2(8) + 8
l = 16 + 8
l = 24
Length = 24 inches
Width = 8 inches

L = 8 + 2W
64 = 2L + 2W
64 = 2(8+2W) + 2W
64 = 16 + 4W + 2W
64 = 16 + 6W
64 - 16 = 6W
W = 48 / 6
W = 8
