Question

A fence is 140 feet long and 50 feet wide. How much fencing is needed?

Answer 1

I assume you mean the field is 140x50. So, that being the length and width, add them up. Now double that, because there are 4 sides, not just 2.

Answer 2

Is the fence 50 feet wide? Or is the area to be fenced 50 feet wide?
