plz answer its urgeeentt ​

Answer 1

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.
