Solution:-)
Here, length of rectangle = 20 – (3.5 + 3.5) = 13 m, breadth = diameter of semi circle = 7 m
Diameter of Semi Circle = 7 m, i.e. radius r = 7/2 m = 3.5 m
Area of the garden = sum of areas two semicircular shapes + area of rectangle
Area of the garden = π r2 + Length × Breadth.
And perimeter = Total Length of Outer
Boundary
= Circumference of Circle + 2 × Length of rectangle
Perimeter of the garden = 2 π r + 2 l
Hope it helps you ❣️☑️
