How to calculate Diagonal of a Rectangle?
To calculate the diagonal of a rectangle, add the square of its height to the square of its width, and then take the square root of the result.
Diagonal of a Rectangle = √(a² + b²)
- a - Height
- b - Width
Example: Calculate the diagonal of a rectangle with height of 4 cm and width of 7 cm.
Diagonal = √(a² + b²)
Diagonal = √(16 cm² + 49 cm²)
Diagonal = √(65 cm²)
Diagonal = 8.06 cm
