==section input Calculate the length of the diagonal in a rectangle with one side *[input side1=3] cm and another side *[input side2=4] cm. ==section solution Two sides of a rectangle and the diagonal form a right triangle. The diagonal is the hypotenuse. Since, according to the pythagorean theorem, the length of the hypotenuse is the square root of the sum of squares of the sides, we have *[assign diagonal=sqrt( $side1^2 + $side2^2 ) ] {{{diagonal = sqrt( $side1^2 + $side2^2 ) = $diagonal}}} ==section output diagonal ==section check side1=3 side2=4 diagonal=5
