Hi,

The length of the sides of a square is 10 meters find the length of diagonals+highlight_green%28d%29  of the square 

Applying  Pythagorean theorem:

 10^2 + 10^2 = d^2

   200 = d^2

 +sqrt%28200%29+=+d++    (Tossing out the negative solution for unit measure)

 +sqrt%2825%2A4%2A2%29+=+d++

 +5sqrt%28100%2A2%29+=+d++

 +10sqrt%282%29+=+d++
