A rectangular parking space is marked out by painting three of its sides. If the length of the unpainted sides is 9 feet, and the sum of the length of the two painted sides is 37 feet, then what is the area of the parking space in square feet?

A. 46 sq.ft

B. 81 sq.ft

C. 126 sq.ft

D. 252 sq.ft

Correct Answer :

C. 126 sq.ft

Clearly,we have l=9 and l+2b=37,or b=14 $\therefore $Area=$\left(l\times b\right)=\left(9\times 14\right)sq.ft=126sq.ft$
