8 ft. = 96 in.

let x = width
x + 13 = length

2(x + x + 13) = 96
4x + 26 = 96
4x = 96 - 26
 \frac{4x}{4} =  \frac{70}{4}
x = 17.5 - width
x + 13 = 30.5 - length

Check:
Perimeter = 2l + 2w
96 in. = 2(30.5 in.) + 2(17.5 in.)
96 in. = 61 in. + 35 in.
96 in. = 96 in.

Therefore, the answer are:
30.5 in. = length; and
17.5 in. = width
