Question

7
3.5 m
-D
7 m
solution: Length of the middle rectangle = 121 - (35 +3.5)) m
14 m
The diameter of the semicircle is 7 m. hence its radius is 3.5 m.]
Area of the rectangular part = length x breadth
= 14 x 7 m=98 m
Area of the semicircular portions =
Ir = radius of semi-circle]
243.5x3.5 m = 38.5 m
So, total area = (98 + 38.5) m = 136.5 m
The perimeter will be equal to the perimeter of the circle and twice the length of the rectangle.
Perimeter of the circle = 21
22
x3.5 = 22 m
= 2x
Perimeter of the garden = (22 + 14 + 14) m
- 50 m
