Answer:2921.625m²
Step-by-step explanation:
Area of lawn= area of reatangle + 2×Area of Semicircle
- Area of Rectangle= Length × Breadth
=56×35
=1960 m²
2. Area of semicircle=πr²÷2
As Semicircles are attached by breadth
∴diameter of semicircle=35
∴radious=17.5
∴Area = (π×17.5×17.5)÷2
= (3.14×17.5×17.5)÷2
=(961.625÷2)m²
Area of lawn= area of reatangle + 2×Area of Semicircle
=1960+ 2×(961.625÷2)
=∴1960+961.625
=2921.625m²
NO dear if we connect semicircle by Length then answer will be 3656
