math question but dont get one part of it?
For a long time, Tom’s wife has complained that the farm animals get into her vegetable patch, trampling and eating the vegetables. Tom’s solutions is to fence in the garden to keep the animals out. Looking in his shed, he discovers that he has a roll of fencing mesh that is 40 metres long.
Being a practical man, Tom wants to make the best use of the fencing mesh and provide his wife with the largest garden possible. He is only prepared to make a rectangular fence, and the side dimensions must be whole numbers.
Using the 16 metre wall as an entire or partial edge to the garden, and the 40 metres of fencing mesh, investigate the possible rectangular fences that can be constructed to produce a larger vegetable patch for Tom’s wife. Draw a diagram of the final design showing the dimensions and how much of the shed’s wall was used.
*** i do not understand what it means by “Using the 16 metre wall as an entire or partial edge to the garden” could someone please explain that bit.
Only 3 sides of the rectangle require fencing because the wall will provide the fourth side.
Note that you can use all the wall, or less than all the wall, as the fourth side.
