Let sides be L and B
L = B + 4
2L + 2B = 92
2(B + 4) + 2B = 92
2B + 8 + 2B = 92
4B = 84
B = 21 m
L = 25 m

P = 2(l + w)
2(w + 4 +w)
=2(2w + 4) = 92
= 2w + 4 = 46
= 2w = 42
w = 21 m
l =25 m

perimeter = 2 length + 2 width
since length is width +4
perimeter = 2(width +4) + 2 width
92m = 2width + 8 + 2width
84m = 4 width
width = 21m
since Length = width + 4
Length = 25m

2x + 2(x+4) = 92
4x = 92-8
x = 84/4
x = 21 width
4 + 21 = 25 length

p = 2l + 2w = 92
l = w + 4
92 = 2(w + 4) + 2w
92 = 2w + 8 + 2w
84 = 4w
w = 21m
l = 25m
