Hi,
The length of the sides of a square is 10 meters find the length of diagonals{{{ highlight_green(d)}}}  of the square 
Applying  Pythagorean theorem:
 10^2 + 10^2 = d^2
   200 = d^2
 {{{ sqrt(200) = d  }}}    (Tossing out the negative solution for unit measure)
 {{{ sqrt(25*4*2) = d  }}}
 {{{ 5sqrt(100*2) = d  }}}
 {{{ 10sqrt(2) = d  }}}
