Question

Mr. Robredo is building a fence around a rectangular region with 36 feet of fencing. The area of the rectangular region is 65 square feet. What are the length and the width of the rectangular region?

Answer 1

In order to answer this problem, we need to find a combination of length and width that would have an area of 65 feet^2 and 36 feet.  So far, we know that 65=l*w and 36=2l+2w.  The answer is the length is 5 and the width is 13.  We can check our work.

5*13=65
2(5)+2(13)=10+26=36
