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?
Options:
A . 126 sq. ft.
B . 64 sq. ft.
C . 100 sq. ft.
D . 102 sq. ft.
Answer: Option A
Answer : Option A
Explanation :
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.
