The length and breadth of a square are increased by 30% and 20% respectively. The area of the rectangle so formed exceeds the area of the square by:

Explanation

Let the side of square = ‘x’ Area of square = x2 New length of rectangle = 130 x 100 New Breadth of rectangle = 120 x 100 130 120 2 ´ ´ x Hence, Area of so formed rectangle = 100 100 156 x 2 = 100 Therefore, area of rectangle exceeds the area of square by 56%
