Question

Find the area of a rhombus having diagonals of length 10 cm and 20 cm.

• A. 100 cm²
• B. 200 cm²
• C. 400 cm²
• D. 50 cm²

Answer 1

The correct option is A

100 cm²

Let d₁ and d₂ be the length of the two diagonals of a rhombus.

Area of the rhombus

$=\frac{1}{2}$ $\times$ d₁ $\times$ d₂

$=\frac{1}{2}$ $\times$ 10 $\times$ 20

$=100c{m}^2$
