Question

The area of a rhombus is 240 cm² and one of the diagonals is 16 cm. Find the other diagonal.

Answer 1

Let length of one diagonal d₁ = 16 cm and

length of the other diagonal = d₂

Area of the rhombus = `1/2` d₁.d₂ = 240

So, `1/2` 16 d₂ = 240

Therefore, d₂ = 30 cm

Hence the length of the second diagonal is 30 cm.
