The perimeter of a square is 48 cm. The area of a rectangle is 4 cm2 less than the area of the square. If the length of the rectangle is 14 cm, then its perimeter is  Select
A) 42	B) 48	C) 52	D) 56	E) 58
Side of the square = 12 cm. Area of the rectangle = [(12 x 12) Ã¢â‚¬â€œ 4]   cm2 = 140 cm2   Now, area = 140 cmÂ², length = 14 cm.   Breadth = A/L = 140/14 cm. = 10 cm.   Hence, Perimeter = 2 (l + b) = 2 (14 + 10) cm = 48 cm.   Answer :48
