Answer 2

£57.6

Explanation:

Given :The pen must have a perimeter of 24 m

Every half meter of fencing costs him £1.20

To Find : Work out the cost of the fence used to make the sheep pen.

Solution :

Cost of fencing 0.5 m = £1.20

Cost of fencing 1 m =
`(1.20)/(0.5)=2.4`

The pen must have a perimeter of 24 m

So, cost of fencing 24 m =
`2.4 * 24 = 57.6`

Hence the cost of the fence used to make the sheep pen is £57.6
