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?
Options.
A) 46	B) 81	C) 126	D) 252	E) None of these
Clearly, we have : l = 9 and l + 2b = 37 or b = 14.   ∴ Area = (l × b) = (9 × 14) sq. ft. = 126 sq. ft.   Answer 126
