Question

Mark (✓) against the correct answer
The lengths of the diagonals of a rhombus are 18 cm and 15 cm. The area of the rhombus is

(a) 270 cm²
(b) 135 cm²
(c) 90 cm²
(d) 180 cm²

Answer 1

(b) 135 cm²

Area of the rhombus = $\frac{1}{2}$ × (Product of the diagonals)
= $\left(\frac{1}{2}\times 18\times 15\right)$ cm² = 135 cm²
Hence, the area of the rhombus is 135 cm².
