Answer:
Answer - 550 m^2
Step-by-step explanation:
Radius of circular field = 20m
As, we know area of circle is given by the formula → πr²
So, Area of circle = (22/7) (20)²
= (22/7)(400)
= 1257.14 m²
If the width of path is 5m then the radius of circle when we remove the path = (20-5)m
= 15m
Area of circle without path
= (22/7)(15)²
=( 22/7)(225)
=707.14 m²
So, The area of path will be →
Area of whole circle - Area of circle without the path
= 1257.14 - 707.14
= 550 m²
