A duck farmer wishs to build a rectangular enclosure of area 100m² . The famer must purchse wire netting for three of the sides, as the fourth side is an existing fence. Naturally, the farmer wishes to minimise the length (and therefore cost) of fencing required to complete the job.

If the sides adjacent to the existing fence have length x m, Write the equation for the length of wire netting to be purchased.

(in paper it will be L =, and we will use L for the following problems )
