Question 150866
If a pool table measures 4ft by 8ft, what is the length from the back edge of the top left pocket to the bottom right pocket to the nearest tenth? 
A. 80ft B. 24.3ft C. 6.9ft D. 8.9ft 
It also says to make a sketch.
How should I do that? 
By drawing a rectangle then label the top and the bottom of the rectangle 4ft and the sides of the rectangle 8ft?
----------------------------
Draw a rectangle that is not a square.
Let the shorter side be 4 ft.
Let the longer side be 8 ft.

Use the Pythagorean formula to find the diagonal.
d^2 = 4^2 + 8^2
d^2 = 16 + 64
d^2 = 80
d = sqrt(16*5)
d = 4sqrt(5)
d = 8.94 ft
