HI BUDDY

area \: of \: the \: figure = area \: of \: rectangle \:  +  \: 2 \times area \: of \: one \: semicirle \\ area = l \times b + 2 \times \  \frac{\pi {r}^{2} }{2}  \\ area = l \times b + \pi {r}^{2} \\ here \: l =  \: 20m \:  \:  \: b = 7m \:  \:  \: \\  r =  \frac{7}{2} m \: (diameter \: of \: the \: semicircle = breadth \: of \: the \: rectangle) \\ area = 20 \times 7  +  \frac{22}{7}  \times  \frac{7}{2}  \times  \frac{7}{2}  \\ area = 140 +  \frac{77}{2}  \\ area = 140 + 38.5 \\ area = 178.5 {m}^{2}  \\  \\ now \\ perimeter = 2 \times length \: of \: rectangle + 2 \times circumference \: of \:  \\ semicircle \\ perimeter = 2l + 2 \times  \frac{2\pi \times r}{2}  \\ perimeter = 2l + 2\pi \times r \\ perimeter = 2 \times 20 + 2 \times  \frac{22}{7}  \times  \frac{7}{2}  \\ perimeter = 40 + 22 \\ perimeter = 62m \\  \\ hope \: this \: helps \\  \\ please \: mark \: as \: brainliest
