Question

Length and breadth of a rectangular Park is 40 m and 35 m. find the cost of fencing the park at the rate of rupees 50 per metre square.​

Answer 1

Answer:

₹7200 is the cost of fencing the rectangular park.

Step-by-step explanation:

Length of rectangular park = 175 m

Breadth of rectangular park = 125 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 125)

= 2 x 300 = 600 m

Since, cost of fencing park per meter = Rs. 12

Therefore, cost of fencing park of 600 m = 12 x 600 = Rs. 7,200

Answer 2

Here the length and breadth of a rectangular park is given

Length = 40 m

Breadth = 35 m

We will first find the length of fencing that would be needed

For this we will find the perimeter

Perimeter = 2 ( length + breadth )

= 2 ( 40 + 35)

= 2 × 75

= 150 m

Now, the cost of fencing per meter is Rs. 50

So, cost of fencing the park = 150 × 50

= Rs.7500

Hence, the cost of fencing the park will be Rs. 7500.
