Sides of a parallelogram are in the ratio 5 : 4. Its area is 1000 sq. units. Altitude on the greater side is 20 units. Altitude on the smaller side is
-
- 30 units
- 25 units
- 10 units
- 15 units
- 30 units
Correct Option: B
Using Rule 11,
Let the sides of parallelogram be 5x and 4x. Base × Height
= Area of parallelogram
∴ 5x × 20 = 1000
| ⇒ x = | = 10 | |
| 5 × 20 |
⇒ Sides = 50 and 40 units
∴ 40 × h = 1000
| ⇒ h = | = 25 units | |
| 40 |
