of the road figure, find the area
given
3.5
8cm​

Answer 1

Answer:

area of shaded portion =

area of square - area of circle =

${side}^{2} - \pi \: {r}^{2} \\ given : side \: of \: square = 8cm \: and \\ radius \: of \: circle \: (r) = 3.5cm \\ {8}^{2} - \frac{22}{7} \times {3.5}^{2} \\ = 64 - \frac{22}{7} \times 12.25 \\ = 64 - 38.5 = 25.5cm^{2}$

hence the area of shaded portion is 25.5 cm ²
