Find the area of the shaded region shown in the figure

Answer 1

Answer:

Step-by-step explanation:

Let us divide the figure into a semicircle and a rectangle

Area of rectangle=l*b=8*4 m²=32 m²

Radius of semicircle=6-4 m=2 m

Area of semicircle= π*r²/2

                             =4π/2=2π m²=6.28 m² approx

Total area = 32+6.8 m²

                =38.8 m²

Answer 2

Area of rectangle =
$l \times b = 8 \times 4 = 32 {m}^{2}$


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

$= 2\pi = 6.28$
approximately


Therefore area of figure =

$32 + 6.28 = 38.28 {m}^{2}$
