Question

A goat is tied to a cornor of a rectangular plot of dimension 14m*7m with a 21 m long rope. it cannot graze inside the plot, but can graze outside it as far as it is permitted by the rope .find the area it can graze??(in m^2)​

Answer 1

Answer:343 m^2

Step-by-step explanation:

A rectangular plot ABCD has area 14*7 = 98m^2

Now, a goat is tied to any corner lets take it B

Rope is 21 m long

So goat can herd around a circle

So area = pie(radius)^2

= 22/7*21*21*= 1386m^2

Area of graze = Area of circle - Area of rectangle

1386- 98

= 1288m^2

Answer 2

Answer:

The final area is $1288^{2}$

Step-by-step explanation:

To find out the total graze need to put the value in the formula:

=Area of circle - Area of rectangle

Given:

The dimension of the plot is 14x7 and the rope which is 21m long.

Find:

Need to find out the graze area which can be used by the goat.

Solution:

Total rectangular plot area is:

$14*7 = 98m^2$

The area which have:

$area = pie(radius)^2= 22/7*21*21\\= 1386m^2$

To find out the area of graze put values in the formula

$Area of circle - Area of rectangle \\1386- 98= 1288m^2$
