Question

Determine the area of MNOP if NP = 17cm

Answer 1

Check the picture below.

`\stackrel{ \textit{\LARGE Areas} }{\stackrel{ \textit{upper triangle} }{\cfrac{1}{2}(\underset{b}{17})(\underset{h}{11})}~~ + ~~\stackrel{ \textit{lower triangle} }{\cfrac{1}{2}(\underset{b}{17})(\underset{h}{9})}}\implies 93.5+76.5\implies \text{\LARGE 170}~cm^2`
