The diagonals of a rhombus are 8 cm and 10 cm. Then the area of the rhombus is

Correct option is D

Given:

The diagonals of the rhombus are d₁ = 8 cm and d₂ = 10 cm.

Formula Used:

​$$A = \frac{1}{2} \times d_1 \times d_2$$​​

Substitute the given values into the formula:

​$$A = \frac{1}{2} \times 8 \times 10 = 40 \, \text{cm}^2$$​​

Thus, the area of the rhombus is:

A = 40 cm²
