Question

The area of a rhombus is 240 sq.cm. If one of its diagonals is 16 cm, then the length of its other diagonal is :
(A) 30 cm
(B) 17 cm
(C) 16 cm
(D) 15 cm

Answer 1

Hope this helps you

Answer 2

Solution :

Let d1, d2 are two diagonals of a

rhombus .

given d1 = 16 cm ,

d2 = ?

Area of the Rhombus (A) = 240 cm²

=> ( d1 × d2 )/2 = 240

=> ( 16 × d2 )/2 = 240

=> d2 = ( 240 × 2 )/16

=> d2 = 30 cm

Therefore ,

Option ( A ) is correct.
