Answer:
perimeter of the semicircle
= 2πr /2 + 2r
= 22/7 × 14/2 + 14
= 22 + 14
= 36 m
area of the semicircle
= 1/2 πr^2
= 1/2 ×22/7× (14/2) ^2 [since radius = diameter/2]
= 1/2 × 22/7 × 49
= 11× 7
= 77 m^2

diameter for semicircle is 14 m
radius = 14/2 = 7 m
perimeter of Semicircle = πr + 2r
=> 3.14 × 7 + 2×7
=> 21.98+14
=> 35.98 m
Area of Semicircle = πr²/2
=> 1.57 × 7 × 7
=> 76.93 m²
