Question

A horse is tied at the center of a rectangular field of dimension 60m x 30m by means of a 21m long rope. Find:
a) the area grazed by the horse.
b) the area not grazed by the horse.

Answer 1

Answer:a)ans:1386 m^2 , b) ans:414 m^2

Step-by-step explanation:

According to question,we have a rectangle having dimensions:-

Length , l = 60m

Breadth, b = 30m

Then, Area of Rectangle=l x b

=60m x 30m

= 1800 m^2

tHerefore, area of whole field = 1800 m^2

Now,

a). area of field grazed

=>pie r^2 [where, r =21m (given)]

=> 22/7 x 21m x21 m

=>1386 m^2

b). area of field not grazed

=> area of total field - area of grazed filed

=> 1800 m^2 - 1386 m^2

=>414 m^2
