A kitchen table has length that is two feet less than twice its width. If a table cloth with an area less that 26 square feet covers the table top, what is the length of the table?

l=2w2
A=lw=(2w2)(w)=2w^22w<26
2w^22w<26
2w^22w26<0
3.14005<w<4.14005, substitute in the first equation to find the value of l
8.2801<l<6.2801
