The diagonal of a small square tabletop is 30 inches long. What is the length of each side of the tabletop in inches?
----
Draw the square ; draw the diagonal (label it 30 inches)
---
Label the sides: s, s, s, s
----
Use Pythagoras to solve for "s"::
s^2 + s^2 = 30^2
------
2s^2 = 900
s^2 = 450
s = sqrt(450) = sqrt(2*225)) = 15sqrt(2)
