Correct Answer: 44%
Explanation:
Original area = (xy) m2.
| New length = | ❨ | 120 | x | ❩m | = | ❨ | 6 | x | ❩m. |
| 100 | 5 |
| New breadth = | ❨ | 120 | y | ❩m | = | ❨ | 6 | y | ❩m. |
| 100 | 5 |
| New Area = | ❨ | 6 | x x | 6 | y | ❩m2 | = | ❨ | 36 | xy | ❩m2. |
| 5 | 5 | 25 |
The difference between the original area = xy and new-area 36/25 xy is
= (36/25)xy - xy
= xy(36/25 - 1)
= xy(11/25) or (11/25)xy
| ∴ Increase % = | ❨ | 11 | xy x | 1 | x 100 | ❩% | = 44%. |
| 25 | xy |
