We have that the total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]
From the question we are told that:
Number of tables [tex]n=36[/tex]
Length of table[tex]l=8[/tex]
Extension [tex]e=3 inch =>0.25feet[/tex]
Generally, the equation for the Total length tables is mathematically given by
[tex]l_t=n*l\\\\l_t=36*8[/tex]
[tex]l_t=288ft[/tex]
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]
[tex]X=288.5ft[/tex]
In conclusion
The total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]
