C++ Program to Find Diagonal of a Rectangle

In this video, we will write a C++ program to find the diagonal of a rectangle.

Formula:
Diagonal = length*length + breadth*breadth

Example:

Input: 
length = 4 & breadth = 3

Output: The Diagonal = 5

Dry run:

We know that the diagonal of a rectangle is sqrt (a*a+ b*b)
So given that here length = 4 and Breadth = 3
=> diagonal of a rectangle is sqrt (4*4+ 3*3)
=> sqrt(16+9)
=> Sqrt(25)
=> So the diagonal of a rectangle is 5.

Here in this video, we will calculate the diagonal of a rectangle using a simple formula.
