SOLUTION: The length of a rectangular garden is 10 feet longer than its width. If the garden's perimeter is 204 feet, what is the area of the garden in square feet?
W + (W+10) = 204/2 = 102 (half of the perimeter).
Hence,
2W = 102-10 = 92 -----------> W = 92/2 = 46.
W = 46; L = 46+10 = 56.
The area = 46*56 = use your calculator.
