SOLUTION: The length of a rectangular garden is 10 feet longer than its width. If the garden's perimeter is 208 feet, what is the area of the garden in square feet?
Perimeter = 208 = L + W + L + W =
(W+10) + W + (W+10) + W = 4W + 20 =================>
4W + 20 = 208 ====> 4W = 208 - 20 = 188 ====> W = = 47.
Answer The width W = 47 ft. The length L = 47 + 10 = 57 ft.
