Question

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

Answer 1

Perimeter of the rectangular park = 2(l+b)

= 2(175+125) m

= 2(300) m

= 600 m

Cost of fencing = 600 × ₹12  = ₹7200

∴ ₹7200 is the cost of fencing the rectangular park.

Answer 2

Answer:

7200 Rs.

Step-by-step explanation:

According to the question,

length of a rectangular park, l = 175 m

and breadth, b = 125 m

Rate of fencing = 12 per meter

We need to find the perimeter of rectangular park.

we know that,

Perimeter of park = 2(l + b)

                             = 2(175 + 125)

                             = 2 x 300

                             = 600 m

length of wire required = perimeter of park

                                       = 600 m

Now,

cost of the fencing 1 m wire = 12 Rs.

So, cost of the fencing 600 m wire = 600 x 12

                                                          = 7200 Rs.

Hence cost will be 7200 Rs to fence the park.
