Question

Please solve it for me please​

Answer 1

Area of rectangle = l × b
length of rectangle = 20 - (3.5 +3.5)
length = 13m
breadth = 7 m
Area = 13×7
Area = 91 m²
____________________
There are 2 semicircles in the figure each diameter is 7 m
2 semicircle = 1 circle
hence, radius = 7/2
____________________
Area of circle = π r²
Area = (22/7) × (7/2)²
Area = 77/2
Area = 38.5m²
____________________
Area of whole figure = Area of rectangle + Area of circle
Area = 91 + 38.5
Area = 129.5 m²
____________________
Perimeter of garden = 2 (length of rectangle) + perimeter of circle
____________________
Perimeter of circle = 2πr
Perimeter = 2 × 22/7 × 7/2
Perimeter = 22m
____________________
Perimeter of the garden =
2(13) + 22
26 + 22
48m
