Step-by-step explanation:
Given: Total length = 20 m
Diameter of semi circle = 7 m
Radius of semi circle = 7/2 = 3.5 m
Length of rectangular field
= 20-(3.5+3.5) = 20-7 = 13 m
Breadth of the rectangular field = 7 m
Area of rectangular field = l×b
= 13×7= 91m2
Area of two semi circles = 2×(1/2)×π×r2
= 2×(1/2)×22/7×3.5×3.5
= 38.5 m2
Area of garden = 91+38.5 = 129.5 m2
Now Perimeter of two semi circles = 2πr = 2×(22/7)×3.5 = 22 m
And Perimeter of garden = 22+13+13
= 48 m. Answer
4. A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area 1080 m2? [If required you can split the tiles in whatever way you want to fill up the corners]
48m
