Answer 1

hope hope it will help you

Answer 2

i) Perimeter of quadrant of semicircles = 2pi r/4 + 14 +14

Perimeter of quadrant of semicircles = 22 + 14 + 14

Perimeter of quadrant of semicircles = 50cm

ii) perimeter of figure = pi 21/2 + pi 14/2 + 21 + 14

perimeter of figure = 33 + 22 + 21 + 14

perimeter of figure = 90cm
