You can put this solution on YOUR website! What is the length of a diagonal of a rectangular picture whose sides are 12 inches by 17 inches
-------------
Draw the picture.
You have a rectangle with base = 17 and height = 12
Draw a diagonal.
Use Pythagoras to get::
d = sqrt[12^2 + 17^2] = sqrt(433) = 20.81 inches
