Question

Find the area of rhombus whose diagonals are of length $30cm$ and $20cm$.

Answer 1

If $d_1$ and $d_2$ are the lengths of the diagonals of a rhombus then its are is given as $\frac{1}{2}\times d_1\times d_2$.

Here, $d_1=30$ cm and $d_2=20$ cm

Let $A$ be the area of rhomus.

$A=\frac{1}{2}\times 30\times 20$ $c{m}^2$

$=300$ $c{m}^2$
