Question 248469
<font face="Garamond" size="+2">


I have no idea what a diaganol is -- some new cholesterol lowering medication maybe?  However, the diagonal of a square creates an isosceles right triangle with two of the sides. Use Pythagoras:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ \sqrt{5^2\ +\ 5^2}]


You can do your own arithmetic.
