Say I've got a rectangle measuring $140$ cm (height) x $300$ cm (width). What is the distance from the top left corner, to the bottom right corner? And whats the formula for calculating the distance?

Also: What is the angle in degrees of the line drawn between the two corners?

    You can just use the Pythagorean theorem for this: $d$=$\sqrt{140^2+300^2}$. The angle in the bottom right corner is given by $\theta$=$\tan^{-1}$$140\over300$ or about 25 degrees.2011-04-17
