The area of a square garden is A square feet and the perimeter is p feet. If a=2p+15, what is the perimeter of the garden, in feet?  Choose the correct choice from the following choices:	A) 28	B) 36	C) 40	D) 56	E) 64
Perimeter of square = P   Side of square = P/4   Area of Square = (P^2)/16 =A   Given that A = 2P + 15   (P^2)/16 = 2P + 15   P^2 = 32P +240   P^2 -32P -240 = 0   P^2 -40P + 6P -240 = 0   P(P-40)+6(P+40) = 0   (P-40)(P+6) = 0   P = 40 or- 6   Discarding negative value , P = 40   Answer is 40
