Question

A goat is tied to a pole fixed at the mid - point of the length of a rectangular grassy field of dimension 60m * 30m by means of a 21m long rope. Find the area of the field that is grazed by the goat

Answer 1

Answer:

dares of rectangle is 1800 m²

rope length is 21

so area of graze is a semicircles part with radius 15 m

so area is

$\pi \times r ^{2} \div 2$

3.14×21×21÷2

692.37m²

Answer 2

Answer:

Area of the rectangle = 1800 m²

Rope length = 21 m

So the area of graze is a semicircle path with a radius of 15 m

Area = 3.14×21×21÷2

        = 692.37m²
