Question

calculate the area of a rhombus whose diagonal are 13 and 16cm​

Answer 1

The area of rhombus = 1/2×d1×d2

Where diagonal d1 = 12 cm and d2 = 16 cm

The area of rhombus = 1/2×12×16

The area of rhombus = 96 cm²

Therefore, the area of rhombus = 96 cm²

Answer 2

$\sf \: \large \: \: Area \: of \: rhombus \: = \frac{1}{2} \times d {}^{1} \times d {}^{2}$

We have given that

In a rhombus

diagonal ¹ ( d¹ ) = 13 cm

diagonal ² ( d ² ) = 16 cm

So ,

$\sf \: Area \: of \: rhombus = \frac{1}{2} \: \times 13 \times 16 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: = 13 \: cm \times 8 cm\\ \\ \sf \: = 108 \: cm \: {}^{2}$

Hence the area of rhombus is 108 cm ²
