Question

Find the area of the following shape.

Answer 1

The given figure covers the area of a rectangle of dimensions $18cm\times 3cm$ and a triangle with $(10-3)=7cm$ altitude and base $18cm$.

Therefore,

Area of the given shape $=$ Area of rectangle $+$ area of triangle

$\therefore$ Area of given shape $=length\times breadth+\frac{1}{2}\times base\times height$

$=(18\times 3)+(\frac{1}{2}\times 7\times 18)$

$=24+63=87{cm}^2$
