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?

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

Which statements are there
