Question

Let $PQRS$ be a rhombus, with $PR=15cm$ and $QS=8cm$. Find the area of the rhombus.

Answer 1

Area of rhombus $PQRS$ is given by,

$A\left(\square PQRS\right)=\frac{1}{2}\times productofdiagonals$

$A\left(\square PQRS\right)=\frac{1}{2}\times productofdiagonals$

$\therefore A\left(\square PQRS\right)=\frac{1}{2}\times 15\times 8$

$\therefore A\left(\square PQRS\right)=\frac{1}{2}\times 120$

$\therefore A\left(\square PQRS\right)=60sq.cm$
