In a rhombus, whose area is 144 sq.cmone of its diagonal is twice as long as the other, The lengths of its diagonals are ?
-
- 24 cm, 48 cm
- 12 cm, 24 cm
- 6 √2 cm, 12√2 cm
- 6 cm, 12 cm
Correct Option: B
Area of rhombus = (d1 x d2) / 2
⇒ (d x 2d ) / 2 = 144
⇒ d2 = 144
⇒ d = 12
∴ Length of diagonal = 12 cm, 24 cm
