Answer:
perimeter = 62
area=178.5
Step-by-step explanation:
primeter=2πr+40 (2 sides of rectangle)
= 2*22/7*7/2+40
=22+40=62m
area=πr²+(length *breadth)
= 22/7*7/2*7/2 +( 20*7)
=77/2+140
= 178.5m²

Total area of the garden = Area of the rectangular portion + The sum of the areas of the pair of semi-circles
Perimeter of the garden =2× length of rectangular portion + circumference of the circle
