It can be calculated by using the same formula that we use to calculate its area. Area and is denoted by A symbol. The diagonal of a rectangle is determined by the following formula d a2 b2 d a 2 b 2 where a a and b b are the length and width of the rectangle respectively.
As you can see a diagonal of a rectangle divides it into two right triangles BCD and.
Area and is denoted by A symbol. Youll be able to see the 2 triangles that make up the rectangle now. If you know side lengths of the rectangle you can easily find the length of the diagonal using the Pythagorean Theorem since a diagonal divides a rectangle into two right triangles. If diagonal of a rectangle with sides.
