Thus, the diagonal of a rectangle formula is: Let the length of each diagonal be "d".Īpplying Pythagoras theorem to the triangle ABD, Let us consider a rectangle of length "l" and width "w". The diagonal of a rectangle formula is derived using Pythagoras theorem. The length of diagonals of a rectangle can be calculated as, The lengths of both AC and BD are the same. In the following rectangle, AC and BD would be the diagonals. A diagonal cuts a rectangle into 2 right triangles, in which the sides are equal to the sides of the rectangle and with a hypotenuse. You can see that the lengths of both AC and BD are the same.

In the following rectangle, AC and BD are the diagonals. The diagonal of a rectangle is a line segment that joins any two of its non-adjacent vertices. What is the Diagonal of Rectangle Formula? Let us learn the diagonal of the rectangle formula along with a few solved examples.

The formula for the diagonal of a rectangle gives the length of the diagonal when the dimensions of the rectangle are known. Before going to know what is the diagonal of a rectangle formula, let us understand what is meant by the diagonal of a rectangle.
