Given :-
- A rectangular field of dimensions 70 m × 50 m.
- A cow is tied in one corner by a rope of length 21 m.
To Find :-
- The area of the field on which the cow could not graze.
- The perimeter of the field on which the cow could not graze.
Formula Used :-
Given that,
Dimensions of field are
Length = 70 m
Breadth = 50 m
Now,
Cow is tied at one corner by a rope of 21 m.
So,
Radius, r = 21 m
Hence,
Area of field grazed by cow is
Hence,
Area of field not grazed by cow is given by
Now, we have to find the Perimeter of field not grazed by cow,
So,
Required Perimeter is
