Question

The area of the rhombus whose diagonals are of lengths $15cm$ and $12cm$ respectively$,$ is $:$

• A. $135c{m}^2$
• B. $180c{m}^2$
• C. $90c{m}^2$
• D. $105c{m}^2$

Answer 1

The correct option is C

$90c{m}^2$

It is given that diagonals of a rhombus are $15cm$ and $12cm$

Area of the rhombus $=\frac{1}{2}\times d_1\times d_2$ where $d_1$ and $d_2$ are the diagonals of a rhombus$.$

$=\frac{1}{2}\times 15\times 12$

$=15\times 6$

$=90c{m}^2$

Hence, the area of the rhombus is $90c{m}^2$ therefore option $C$ is correct
