Find the altitude of the rhombus whose area is 315 cm² and its perimeter is 180 cm.
- 7
- 18
- 14
- 8
The correct answer is: 7
Since, the perimeter of rhombus = 180 cm
Therefore, side of rhombus = = 45 cm
Now, area of rhombus = b × h
⇒ 315 = 45 × h
⇒ h =
⇒ h =7 cm
Therefore, altitude of the rhombus is 7 cm.
