Question

15. The shape of a garden is rectangular in the middle and semi-circular at the ends as shown in the figure.
Find the area and the perimeter of this garden.
8.4 m
21m ​

Answer 1

Given,

• 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,

$→ 13 × 7 = 91 m²$

• Area of two semi circles,

$→ 38.5 m2$

Area of garden,

$→ 91 + 38.5 = 129.5 m²$

Now Perimeter of two semi circles =  = 22 m

And Perimeter of garden

= 22 + 13 + 13

= 48 m

Answer 2

Step-by-step explanation:

Area of rectangular = Length × breath

21m × 8.4 m = 176.2m

Perimeter of rectangle= 2×(length+breath)

2×(21+8.4)=2×29.4=58.8ans
