The length and breadth of a square are increased by 40% and 30% respectively. The area of the resulting rectangle exceeds the area of the square by:
- 35%
- 42%
- 62%
- 82%
- 92%
Explanation
Let the side of the square = 100 m So area of square = 100 x 100 = 10000. New length = 140 m, New breadth = 130 m previous area= 100x100m2 new area= 140x130m2 so we can find: Increase in area = [(140 x 130) - (100 x 100)] m2 = 8200 m2 ∴ Required increase percent = (8200/ 10000) x 100 % = 82%.
