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, find out the area of the parking space in square feet?
126 sq. ft.
64 sq. ft.
100 sq. ft.
102 sq. ft.
Explanation:
Let l = 9 ft.
Then l + 2b = 37
=> 2b = 37 - l = 37 - 9 = 28
=> b = $\dfrac{28}{2}$ = 14 ft.
Area = lb = 9 × 14 = 126 sq. ft.
