Answer 1

Answer:

The cow which is tied for grazing inside a rectangular field of 80 m × 50 m by means of a rope 21 m, can graze in a area of 1386 sq.m.

Step-by-step explanation:

Here the cow can graze in a circle whose radius is 21m.

So, the total area in which it can graze is

πr^2=22/7×21×21 sq.m

=22×21×3 sq.m

=462×3 sq.m

=1386 sq.m
