Answer 1

Answer:

Diagonal of the quadrilateral = 20 cm

Perpendicular to its diagonal from the other vertex are (h₁=) 9 cm and (h₂=) 15 cm.

Area of the quadrilateral is given by

\begin{gathered}\frac{1}{2}\times (h_1+h_2)\times d\\\\=\frac{1}{2}\times (15+9)\times 20\\\\=\frac{1}{2}\times 24\times 20\\\\=240\ cm^2\end{gathered}
