If the length is 5 feet longer than its width and someone uses 70 feet of fencing, what are the dimensions of the enclosed area?

Question

Thi problem is really giving me trouble could someone please help me ASAP. Thank you

Answer 1

I assume you're speaking of a rectangular area of width w and length w+5. You know that perimeter = 2[w + (w+5)] = 70; from this you can compute (solve for) w.

 

Then area = w(w+5).
