L.O. Solving mathematical puzzles and problems · The farmer checks and he has exactly £134 to build a new rectangular enclosure. He wants to enclose as much grass as possible so that both goats can share the space. · He decides to buy a fence post for each corner of the rectangle and chicken wire for the fencing.

Fence posts cost £3.50 each. Chicken wire costs £2.00 per metre. How long and wide should the rectangle be so the goats can have as much grass as possible?
