I have my work at the bottom but to explain you have to divide 30/12, and I got 2.5. That means 30 is 2.5 times bigger than 12. Because we have to find x, we have to divide 7/2.5, to find what is 2.5 times smaller than 7. That’s 2.8. So, x= 2.8

The cost of fencing a square field at Rs.15 per meter is Rs.360. Find the length of each side of the field.

torisob [31]

Answer:

The lenght of one side= 6

Step-by-step explanation:

The cost of fencing around the field for one meter = 15

The total cost = 360

The perimeter = 360 / 15 = 24 m

The lenght of one side= 6

( p = 4S)

so .... (s = p /4 )

24 = 4s

so .... s = 24/4 = 6

I hope it's right !!!!!
