What is the longest straight line tht can be drawn on an 8 1/2 inch by 11 inch piece of paper?

It's going to be the diagonal from one corner to the other. If you drew that line, you'd have two right triangles. So, use the Pythagorean Theorem.
a^2+b^2=c^2
(8.5)^2+(11)^2=c^2
c=13.9 inches

The diagonal = sqrt (8.5^2 + 11^2) = 13.9 inches

Yes, someone knows this.
But if you want to get nitpicky,
1) all lines are straight, so "straight line" is redundant, and
2) lines are infinite, so you can't fit one on an 8 1/2" x 11" sheet of paper. You mean the longest line segment.

Diagonally across = sqrt (8.5^2 + 11^2) = 13.9 in

using the pythagorian theorem:
a^2+b^2=c^2
8 1/2^2+11^2=c^2
72.25+121=c^2
138.25=c^2
square root it all and the final answer is:
11.76=c (rounded to the nearest hundredth)
