19 cm Nomkhosi wants to start a vegetable garden. The garden will have a
rectangular shape, and will be 8 m long and 3 m wide. She wants to
put a fence around the garden. On each corner a metal post must be
planted, and along the sides, a thin metal post (a “dropper") must be
inserted every metre. Two posts, similar to the corner posts, must be
planted 1 m apart along one length to allow for a gate. Two horizontal
steel wires will be stretched around the camp, except at the gate.
Chicken wire fencing is to be attached to these two wires.
