Perimeter = 2*length + 2*width
So 96 = 2*length + 2*width
So 48 = length+width
We also know length = 2*width
Hence, 48 = (2*width) + width
48 = 3*width
16 = width
... and since length = 2*width, length =32.

the equation for the perimeter is P=2L+2W with L being Length and W being width.
If the L=2W, the put in 2W for L into the equation. Since you know the perimeter is 96, plug it into the equation:
2(2W)+2W=96
4W+2W=96
Solve for W:
6W=96
W=16
since L=2W:
L=2(16)
L=32
The length is 32 and the width is 16

2W + 4W = 96, where W is the width. Obviously, W is 16, and L is 32.

well you need to divide that so that you get two even numbers.
so 26 and 70 would work.
then the Length and Width would be 13 and 35.

2(32)+2(16)=96

l=2w
2l+2w=96
substituting
4w+2w=96
6w=96
w=16
l=2*16=32
