Question

Ravi ties his cow on one corner of his field to graze. It is a rectangular field of length 15 m and breadth 7 m, what is the area the cow can graze? What
is the area left ungrazed?​

Answer 1

${\huge{\underline{\mathcal{\pink{Answer}}}}}$

The area of the square field

= 10^2

= 100 sq m.

The quadrant of the circle that the cow can graze

= [(pi)r^2]/4

= [(22/7)*7^2]/4

= 38.5 sq m.

The area of the field that the cow cannot graze

= 100 - 38.5

= 61.5 sq m
