Remember the original square table?
We can cut the square table diagonally into two triangles.
Find the length of the diagonal.
Find the diagonal using the Pythagoran Theorem:
a2 + b2 = c2 c a
10ft2 + 10ft2 = c2
100ft ft = 200 ft so c2 =200
Square root of 200 = ft
The diagonal is ft

If there are eight sides of the table, and twelve knights, how many knights would be on each side of the table, if you didn’t include the king?
Show your work by writing an equation or drawing a picture to arrive at the answer.
12/8 = 1.5
There can not be half a knight so, some sides will have one person for all sides to be occupied.
