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.
The ratio of the number of miles covered by car a to the number of miles covered by
car b is 1 t0 4.
55 x 5 = 275 words
285 - 275 = 10
10 errors would be expected
