Answer 1

Area of $\Delta DAC=60c{m}^2$... (given)
$\Delta DAC$ and parallelogram ABCD lie on the same base DC and between the parallels AB and DC. [1 Mark]

$\therefore$Area of parallelogram ABCD = $120c{m}^2$ ... (area of a parallelogram is twice the area of triangle if both are on the same base and between the same parallels). [1 Mark]
