Exploring Area Calculations for Rectangles and Parallelograms

This video tutorial introduces the concept of area, focusing on rectangles, squares, and parallelograms. It outlines a four-step checklist for calculating area: writing the formula, substituting values, evaluating, and labeling the answer. The video demonstrates how to find the area of rectangles using length times width or base times height, and explains the unique formula for squares. It also covers the area of parallelograms, emphasizing the importance of using base and height that form a right angle. The tutorial concludes by visually demonstrating why the parallelogram area formula is similar to that of a rectangle.

What is the first step in the area calculation checklist?

• Label the units

• Write down the formula

• Evaluate the expression

• Substitute the values
