Question

Find the cost of fencing a rectangular park of length 250m and breadth 175m at the rate of Rs.12 per meter.​

Answer 1

According to the question:

• As per given in the question length 250m and breadth 175m at the rate of 12 rupees per metre and we are said to find cost of fencing.

Given:

• Length = 250m
• Breadth = 175m
• Cost of fencing = 12 rupees per metre

To Find:

• Cost of fencing a rectangular park

Therefore,

Using formula

$\: \: \sf \: perimeter \: of \: rectangle = 2(length + breadth)$

Substitute the given values

$\: \: \sf \: perimeter \: of \: rectangle = 2(250 + 175) \\ \\ \: \: \sf \: perimeter \: of \: rectangle = 2 \times 425m \\ \\ \: \: \sf \:perimeter \: of \: rectangle = 850m$

Hence, Perimeter of rectangle is 850m.

As given

Cost of fencing 1 metre of park = 12 rupees

Therefore,the total cost of fencing the park = 12 × 850 = 10200 rupees.

Answer 2

Given:-

• Length = 250 m

• Breadth = 175 m

• Rate of fencing = Rs. 12 per meter.

To Find:-

• Cost of Fencing rectangular park

Formula used:-

• Perimeter of Rectangle = 2(l + b)

Solution:-

➤ Perimeter of Rectangle = 2(l + b)

➤ Perimeter of Rectangle = 2(250 + 175)

➤ Perimeter of Rectangle = 2 × 425

➤ Perimeter of Rectangle = 850 m

Cost of Fencing at the rate of Rs. 12 per meter = 850 × 12

⠀⠀⠀⠀= Rs. 10200

Hence, the cost of Fencing at the rate of Rs. 12 per meter is Rs. 10200.
