Here's the question: Jose needs to enclose a rectangular section of his yard. The area is 35 sq. ft. and the perimeter is 27 sq.ft. Find the length and width of the section.
The issue I'm having is that I think I need to find the common fators of 35 and 27 and they have no common factors so I have no idea what the answer is. Can anyone help?
2L + 2W= 27
From the first, L= 35/W put that in the second.
2*35/W + 2W= 27
multipy through by W, and put in quadratic form, and use the quadratic equation or factor.
