Mathematics

Area of Rhombus

Calculate area of a rhombus using its diagonals.

Area = ½ × d₁ × d₂

Formula Explanation

The diagonals of a rhombus bisect each other at right angles; area is half their product.

Variables Explained

d₁, d₂ = lengths of the two diagonals.

Solved Example

Diagonals 10 cm and 8 cm. Area?
½ × 10 × 8 = 40 cm².

Exam Tip

This formula works only with diagonals, not sides.
