Answer:
Step-by-step explanation:
(i) Given, Side of a square=70 m
From the given figure.
The Diameter of the semi-circle =70m
So, Side of square = Diameter of semi-circle =70m
Hence, the perimeter of the lawn =diameter+semiperimeter of circle
=70+1/2×2πr
=290 m
(ii) Area of square =70×70=4900m²
Hence, the required area Area of the square - area of the semicircle
=4900-1/2×π×r²
=4900-1/2×22/7×35²
=4900-1/2×22/7×1225
=4900-1925
=2975 m²
