Given:
A rectangular field with
- Length = 36 m
- Breadth = 28 m
What To Find:
We have to find the
- The cost of fencing at the rate of Rs. 75 per meter.
How To Find:
To find the cost, we have to find the,
- Perimeter of the rectangular field
- Then multiply it with Rs. 75.
Formula For Finding:
- Perimeter = 2(l + b)
Where
- l = length
- b = breadth
Solution:
- Finding the perimeter.
Using the formula,
⇒ Perimeter = 2(l + b)
Substitute the values,
⇒ Perimeter = 2 (36 + 28)
Solve the brackets,
⇒ Perimeter = 2 × 64
Multiply 2 by 64,
⇒ Perimeter = 128 m
- Finding the cost.
To find cost we have to ,
⇒ Cost of fencing = Perimeter × Rs. 75 per meter
Substitute the values,
⇒ Cost of fencing = 128 m × Rs. 75 per m
Multiply 128 by 75,
⇒ Cost of fencing = Rs. 9,600
∴ Thus, the cost of fencing the rectangular field is Rs. 9,600.
