Question

The diagram, given below, shows two path's drawn inside a rectangular filed $80m$ long and $45m$ wide. The widths of the two paths are $8m$ and $15m$ as shown. Find the area of the shaded portion.

Answer 1

Area of shaded region

$=$ Area of rectangle $1+2-$ square $3$

$=(45\times 15)+(80\times 8)-(8\times 15)$

$\left\{Ar\right(rectangle)=length\times breadth,Ar(square)=sid{e}^2\}$

$=675+640-120$

$1195m^2$
