Question

Find the cost of fencing a square park of side 200 m at the rate of Rs. 30 per meter.

Answer 1

Answer:

side of square=200m

perimeter of square=4×side=4×200m=800m

rate of fencing per metre=Rs. 30

total rate of fencing=30×800=Rs. 24000

So the total cost of fencing is Rs24000

Answer 2

Here the measure of the side of a square park is given

side = 200m

We will first find the perimeter of the square park

perimeter of park = 4× side

= 4× 200

= 800m

Now, we have to find the cost of fencing the square park

cost of fencing per meter = rs. 30

cost of fencing 800m = 30× 800

= 24000.

Hence, the cost of fencing the square park will be Rs. 24000
