Answer:
area of garden = 178.5 cm^2
perimeter of garden = 131 cm
Step-by-step explanation:
r = 7/2 cm ; l = 20cm ; b = 7 cm
area of garden = area of rectangle + area of semicircle×2
= l × b + 2 × 1/2 × π r^2
= 20 × 7 + 22/7 × 7/2 × 7/2
= 140 + 38.5
= 178.5 cm^2
perimeter of garden = perimeter of rectangle + perimeter of semicircle×2
= 2 ( l + b ) + 2 × 1/2 × 2πr
= 2 ( 20 + 7 ) + 2 × 22/7 × 7/2 × 7/2
= 54 + 77
= 131 cm
