Question

Find the cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of rupees 12 per metre.​

Answer 1

Given Information:

The length and breadth of rectangular park is 175 m and 125 m.

Need to find out:

The total cost of fencing the park = ?

To calculate the cost of fencing we required perimeter:-

Perimeter of the rectangle = 2 × ( length + breadth)

Perimeter of the rectangle = 2 × (175 m + 125 m)

Perimeter of the rectangle = 2 × 300 m

Perimeter of the rectangle = 600 m

_____________________

Cost of fencing 1 m of park = Rs 12

Therefore,

The total cost of fencing the plot = Rs 12 × 600

The total cost of fencing the plot = Rs 7200

Hence:-

Total cost of fencing the plot is Rs 7200.

Answer 2

Answer:

Total length to be fenced =Perimeter

=2(l+b)

=2(175+125)

=2(300)

=600m

Given cost is Rs.12 Per meter

Total cost =600×12

=Rs7200
