The Definitive Guide to Calculating the Area of a Rectangle or Parallelogram | Formulas, Units, and Accuracy

Area of a Rectangle/Parallelogram

The area of a rectangle is the measurement of the size of the surface enclosed by its four sides

The area of a rectangle is the measurement of the size of the surface enclosed by its four sides. It can also be applied to parallelograms, as they have the same formula for finding their area. The formula for finding the area of a rectangle or parallelogram is:

Area = base * height

In this formula, the base refers to the length of one of the sides of the rectangle or parallelogram, and the height refers to the perpendicular distance between the base side and its opposite side.

To calculate the area, you simply multiply the base by the height, using the appropriate units. For example, if the base of a rectangle is 5 units and the height is 9 units, the area would be:

Area = 5 units * 9 units = 45 square units

It’s important to note that the units of the base and height must be the same when calculating the area. If they are not in the same unit, you will need to convert them to match before performing the calculation.

Additionally, if the shape is a parallelogram, you must ensure that the height you choose is perpendicular to the base. If it is not, you may need to consider using different measurements to accurately calculate the area.

Remember to always include the appropriate units when expressing the area, as it represents a measurement of the surface enclosed by the shape.
