The video tutorial explains how to calculate the area of a rectangle using the formula area = base x height. It covers basic calculations with given dimensions and reverse calculations to find unknown dimensions. Additionally, it demonstrates how to find the area when given a diagonal and one side using the Pythagorean theorem.

What is the formula for calculating the area of a rectangle?

• Area = base + height

• Area = base / height

• Area = base x height

• Area = base - height
