Question

A horse is tied to a pole at a center of a rectangular field by rope of 2m long. What is the area of the portion of the field in which the horse can graze?(pi=22÷7)​

Answer 1

Step-by-step explanation:

area =πr^2

=22/7*2^2

22/7*4

88/7

Answer 2

Length of each side of the square is 15m.

So its area = 152 sq. m. = 225 sq.m.

Now tied to a corner, the horse can graze ¼ part of the circle formed with a radius of 14m.

So the area horse can graze = (22/7) * 142 * (1/4) = 154 sq.m.

The area the horse can’t graze = (225 – 154) = 71 sq.m.

Area of grazing is 153.86 sq.m not 154.86. Hence answer is 71.14 sq.m
