Answer:
- The horse can graze over a area of 154 m².
Step-by-step explanation:
Given that:
- A horse is placed for grazing inside a rectangular field.It is tethered to one corner by a rope of 14 m long.
To Find:
- Area which can grazed by the horse.
Concept:
Here we have been given that, a horse is tied on the corner of a rectangular field with a rope of length 14 m. We have to find the area grazed by the horse.
How to do:
The area which the horse can graze will be 1/4th of the area of a circle with the radius 14 m.
Solution:
As we know that,
Area of a circle = (πr²) sq. units
Where,
- r = Radius
So, area grazed by the horse:
Here,
- r = OA = 14 m
Substituting the values,
Reducing the numbers,
Multiplying,
Dividing,
Hence,
Area grazed by the horse = 154 m²
