How to calculate Area of a Rectangle?
To calculate the area of a rectangle, multiply the length of side "a" by the length of side "b."
Area of a Rectangle = a * b
- a - Height
- b - Width
Example: Calculate the area of a rectangle with height (a) of 6 cm and width (b) of 14 cm.
Area = a * b
Area = 6 cm * 14 cm
Area = 84 cm²
