Question

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

Answer 1

Answer:

let x be the perimeter of the field

so cost per meter × perimeter = total cost

so

x × 35=4480

x=4480/35

x=128

perimeter =128

so the 4×side=128

side =128/4

side=32 meters

so length of each side of the field = 32

Answer 2

Answer:

32

Step-by-step explanation:

Let each side be of x m.

Then the perimeter will be 4x.

The total cost will be (35*4)x $

Then 140x=4480

x=4480/140

=32

Here is your answer, hope it helps.
