Question

Find the area of $\parallel gmABCD$ if the area of shaded region is $12c{m}^2$.

Answer 1

Area of $\Delta APB=12c{m}^2$

$\frac{1}{2}\cdot AP\cdot 3=12$

$AP=8cm$

$So,areaof\Delta CDM=12c{m}^2$

$Areaof\square AMCP=9\times 8c{m}^2=72c{m}^2$

$Areaof\square ABCD=\left(12+12+72\right)c{m}^2=96c{m}^2.$
