Answer 2

Answer:

Area = 714m^2

Perimeter = 152m

Step-by-step explanation:

Hope ! u understand the figure

ABCD is a rectangle

Area of rectangle =Length×Breadth

Area = AD ×AB = 14×40 = 560m^2

Perimeter of rectangle =2(l+b)

Perimeter = 2( AD+AB)

= 2(14+40) = 2×54 = 108m

Area of semicircle=(πr^2)/2 = (22/7×7^2)/2

= (22/7×49)/2 = (22×7)/2

= 154/2 = 77m^2

Area of 2 semicircle= 2×77 = 154m^2

Perimeter of semicircle =πr/2 = 22/7×7 =22m

Perimeter of 2 semicircle= 22×2 = 44m Total area of lawn =560+154 = 714m^2

Total perimeter of lawn = 108+44 = 152m
