Question

If you say the APPROPRIATE answer..I will mark you as the brainliest!!

Answer 1

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]
