Question

The cost of putting a fence around a square field at Rs 35 per metre is Rs 4480. Find the length of each side of the field.

Answer:

Answer 1

Answer:

128 m

Step-by-step explanation:

Length of each side of field=total cost/cost per meter

Total cost=4480

cost per meter=35

Length of each side of field=4480/35

=128 m

Answer 2

Now, perimeter of square =4×side

And the cost of fencing per metre is Rs.35 .

Therefore total cost = perimeter× 35

=4×s×35

But it is given that total cost = 4480

Hence,

4×s×35=4480

140×s=4480

S=4480/140

s=32m

Therefore length of each side is 32m

Hope it helps.
