Answer 1

The area of the garden is the area of the square + twice the area of the semicircle.

It is 13.7 + 2.(1/2).π.(3.5^2)= 91 + (77/5)

= 91 + 15.4 = 106.4 sq metres

The perimeter of the garden is 13.2 + 44 = 70 m.

Answer 2

Answer:

129.5 m^2, 48 m

Step-by-step explanation:

Diameter of semi circle = 7 m

Radius of semi circle = 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 = 13 * 7 = 91 

Area of two semi circles = 38.5 m^2

Area of garden = 91 + 38.5 = 129.5 m^2

Now Perimeter of two semi circles = 22 m

And Perimeter of garden = 22 + 13 + 13 = 48 m

Hence,

Area of garden = 129.5 m^2

Perimeter of garden = 48 m
