Calculating Areas of Composite Figures

The video tutorial explains how to find the area of composite figures by identifying individual shapes and using their respective area formulas. It covers the calculation of areas for parallelograms, trapezoids, and rectangles, emphasizing the importance of using perpendicular heights. The tutorial also demonstrates how to sum these areas to find the total area of composite figures. Additionally, it provides a brief overview of handling complex shapes and offers resources for further learning.

What is the first step in finding the area of a composite figure?

• Subtract the areas

• Calculate the area of each shape

• Identify the types of shapes

• Add the areas together

Which formula is used to calculate the area of a parallelogram?

• Base times height

• 1/2 base times height

• Base plus height
