Answer:
Hello..
Step-by-step explanation:
Perimeter of the semi circular garden = 180 m
=>
\pi \:r \: + 2r \: = 180 \: mπr+2r=180m
=> r (3.14 + 2) = 180 m
=> r (5.14) = 180 m
=> r = 180 m ÷ 5.14
=> r = 35.01 m
Area of the semi circular garden =
\frac{\pi \: {r}^{2} }{2}2πr2
= (3.14 × 35.01 × 35.01 sq. m) ÷ 2
= 1924.34 sq. m
