Question

Find the area of shaded portion in the adjoining figure:

Answer 1

Step 1: Calculate the area of square and circle

Area of square$={\left(side\right)}^2$

Area of square$=40\times 40=1600c{m}^2$

Also,

Area of circle$=\mathrm{\pi }{\mathrm{r}}^2$

Area of circle$=\frac{22}{7}\times 14\times 14=616c{m}^2$

Step 2:Calculate area of shaded region

Area of shaded portion =$=$ Area of square $-$Area of circle

Area of shaded portion$=1600-616=984c{m}^2$

Hence, area of shaded portion is $984c{m}^2$.
