Question

Draw parallelogram ABCD with the following measurements and calculate its area.
$AC=8cm,BD=6cm$ and $\angle$ COD = ${90}^o$ where $\overline{AC}$ and $\overline{BD}$ intersect at O.

Answer 1

Area of parallelogram ABCD$=2\times ar△ABC$

$=2\times \frac{1}{2}\times 8\times 3$

$=24c{m}^3$
