Question

A dog trainer has 92 ft of fencing that will be used to create a rectangular work area for dogs. If the trainer wants to enclose an area of 304 ft2, what will be the dimensions of the work area?

Answer 1

lw = 304

2(l + w) = 92

 

You need to find two factors of 304 that, when added and multiplied by 2, equal 92.

 

For example, 4(76) = 304, but 2(4 + 76) = 160, so the work area is not 4 x 76.
