Answer:

Semicircle = [tex]\frac{\pi x d }{2} + d[/tex]

semicircle = [tex]\frac{\pi x 20 }{2} + 20[/tex]

semicircle = 51.4

∴ the perimeter is 14 + 32 + 51.4

∴ The perimeter is 97.4 cm

Area 1 = [tex]\pi r^{2}[/tex]

Area 1 = 20 ÷ 2 = 10

Area 1 = [tex]\pi 10^{2}[/tex]

Area 1 = 314.2

Area 2 = 14 × 32 = 448

Area = Area 1 + Area 2

Area = 762.2cm²
