Mensuration
A cow is
tied with a rope of length 14m a one corner of a rectangular field of
dimensions 20m x 15m. find the area of the field in which the cow cannot graze.
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.

ReplyDelete= 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.
