Question 1123328: The perimeter of a standard tennis court used for doubles is 228 ft. The width is 42 ft less than the length. Find the dimensions. Answer by ikleyn(52759) (Show Source):
L + W + L + W = 228 feet (the perimeter)
2L + 2W = 228
L + W = 228/2 = 114.
Substitute W = L - 42.
L + (L - 42) = 114
2L = 114 + 42 = 156
L = 156/2 = 78.
Answer. The dimensions are 78 ft (length) and 78 - 42 = 36 ft (width).
