You can put this solution on YOUR website! A man travels 1 km North, 2 km East, 3 km North, and 4 km East. How far is he from the starting point? ------------------
 That's a total of 4 km North and 6 km East.
 
  d =~ 7.211 km

 ============
 If the lengths of the legs of a triangle are a, b, find the length h of the altitude to the hypotenuse in terms of a and b.
 ------
 c = length of hypotenuse = sqrt(a^2 + b^2)
 ----
 h/b = a/c
 h = ab/c
 h = ab/sqrt(a^2 + b^2)
