Q. The area of a rectangle is 15times of the sum of its length and breadth. If length is 40m, what is the perimeter of the rectangle?
A. 64m
B. 256m
C. 128m
D. 172m
E. None of these

Answer is: C. 128 m 15(40+W)=40W 600+15W=40W W=600/25 = 24... Perimeter of recangle = 2W+2H =2(24)+2(40) =48+80 = 128
