Kurt is building a rectangular deck. if the dimensions of the deck are 10 ft by 23 ft, what the length of the diagonal of the deck?

The length of the diagonal of the deck can solved using the pythagorean theorem because the diagonal the sides of a rectangle will form a right triangle. pythagorean theorem states that
C^2 = B^2 + A^2
where C is the hypotenuse or the diagonal of the rectangles
B and A are the sides of the rectangle

C^2 = 10^2 + 23^3
C^2 = 629
C = 25.08 ft
