Question

The cost of making a boundary line with wind around a square field is rupees 1400 @ rupees 14 per metre find the length of the side of the field

Answer 1

Let the side be x.

Cost for 1m = Rs 14

Here, total cost = Rs 1400

So, length of the boundary or the perimeter= 1400/14 = 100m

We know that, perimeter of a square is 4x.

Hence,

4x= 100

x = 25 m.

Hope it helps!

Answer 2

Step-by-step explanation:

Let side= x

cost for 1m=Rs.14

total cost =1400

length of boundary/perimeter=1400/14=100

P=4x

100=4x

100/4=x

25=x
