Area of the field in which the cow can graze
= πr²/4
= π(14)²/4
= 196π/4
= 49π
= 49 ×22/7
= 154 m²
Area of rectangular field
= l × b
= 20 × 15
= 300 m²
Area of the field in which the cow cannot graze
= Area of rectangular field - Area of the field in which the cow can graze
= 300 m² - 154 m²
= 146 m².
