Perimeter: P = 2L + 2W. In this problem L = W + 4 or W = L - 4. We want L, so let's eliminate W:
P = 2L + 2(L - 4) = 20 (all measurements in feet)
Simplifying,
2L + 2L - 8 = 20, or 4L = 28 ft. Thus, L = 7 ft.
The rectangle is 7 ft long.
Amber should’ve added -3 and 5 first instead of adding 5 and 4.
