5. Nicole is decorating a rectangular dining table for a party. The length of the table is 8 feet and the width is 6 feet. Nicole put a ribbon diagonally across the table. What is the length of theribbon, in feet?

From the problem, we have a rectangular table :
with dimensions 8 feet by 6 feet.
The diagonal is the hypotenuse of the formed triangles.
Using pythagorean theorem :
[tex]c^2=a^2+b^2[/tex]where c is the hypotenuse, a and b are the measurements of two other sides.
That will be :
[tex]\begin{gathered} c^2=6^2+8^2 \\ c^2=36+64 \\ c^2=100 \\ c=\sqrt[]{100} \\ c=10 \end{gathered}[/tex]ANSWER :
10 feet
