Find the area $A$ of a rhombus if diagonal $d_{1} = 0.8 cm$ and diagonal $d_{2} = 2.5 cm$ .

Answer

$1 cm^{2}$

Explanation

To find area $A$ use formula:

A = \frac{d _{1} \cdot d _{2}}{2}

After substituting $d_{1} = 0.8 cm$ and $d_{2} = 2.5 cm$ we have:

A = \frac{0.8 cm \cdot 2.5 cm}{2}

A = \frac{2 cm ^{2}}{2}

A = 1 cm^{2}
