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

Answer:

Rs 7200

Step-by-step explanation:

Length (l) of the rectangular plot = 175 m

Breadth (b) of the rectangular plot = 125 m

The fencing of any field is done on its boundary thus we require the perimeter

Perimeter of the field = 2(l +b)

= 2(175 +125)

= 2(300)

= 600 m

Rate of fencing per meter = Rs 12

Therefore ,

Total cost = Rate of fencing per meter * Perimeter

= 12 * 600

= Rs 7200

Answer 2

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.
