if each foot fencing costs $2.50 , how much does it cost for one side of the fence?

To find out how much it costs for one side of the fence, you need to know the length of that side. Let's assume the length of one side of the fence is 'x' feet.

Given that each foot of fencing costs $2.50, you can multiply the length of one side (x) by the cost per foot ($2.50) to find the total cost.

So, the cost for one side of the fence would be:
Cost = Length * Cost per foot
Cost = x * $2.50
Cost = $2.50x

Therefore, the cost for one side of the fence is $2.50 multiplied by the length of that side (in feet).

Multiply the cost per foot times the length of the fence.
