Question

The area of a rhombus is 28 $m^2$. If its perimeter is 28 m, find its altitude.

Answer 1

Area of rhombus = $28m^2$

Perimeter = $28m$

All sides of a rhombus are equal.

$\therefore 4a=28$

$\therefore a=7m$

Area of a rhombus = $b\times h$

$28=7\times EC$

$\therefore EC=\frac{28}{7}=4m$

$\therefore EC=altitude=4m$
