Question

Please help working out the area of the shaded shape

Answer 1

so the whole rectangle has an area of 22x18, now there's a tiny triangle on the corner, that we can say it has a base of 22 - 19 = 3, and a height of 18 - 14 = 4, so let's get both areas and subtract that of the triangle's from the rectangle's.

`\stackrel{ \textit{\LARGE Areas} }{\stackrel{ rectangle }{(22)(18)}~~ - ~~\stackrel{ triangle }{\cfrac{1}{2}(\underset{b}{3})(\underset{h}{4})}}\implies 396-6\implies \text{\LARGE 390}~m^2`
