A rectangular parking space is marked out by painting three of its sides.If the length of the unpainted side is 9 feet, and the sum of the lengths of the painted sides is 37 feet, then what is the area of the parking space in square feet?
Solution
Correct Answer: Option A
Let l = 9 ft.
Then l + 2b = 37
=> 2b = 37 – l = 37 – 9 = 28
b = 28/2 = 14 ft.
Area = lb = 9 × 14 = 126 sq. ft.
