We are asked to determine the area of the given figure. To do that we will divide the figure into a square and a triangle. The area of the square is the product of its dimension, therefore, the area is:
The area of the triangle is given by the following formula:
Where "b" is the base and "h" is its height. Replacing the values:
The total area is the sum of both areas:
replacing the areas:
We have that the total length of paper needed to cover all the tables is
From the question we are told that:
Number of tables
Length of table
Extension
Generally, the equation for the Total length tables is mathematically given by
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
In conclusion
The total length of paper needed to cover all the tables is
