The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206 m, then its area is
-
- 1520 m²
- 2420 m²
- 2480 m²
- 2520 m²
- 1520 m²
Correct Option: D
Using Rule 9, Let the breadth be x m.
∴ Length = (23 + x) m
⇒ 2 (x + 23 + x) = 206
⇒ 4x = 206 – 46
| ⇒ x = | = 40 m | |
| 4 |
∴ Length = 40 + 23 = 63 m
∴ Required area = 63 × 40 = 2520 m²
