The video tutorial reviews calculating the area of basic shapes like parallelograms, triangles, trapezoids, and rectangles. It introduces composite figures, which are combinations of these basic shapes, and explains how to break them down into known shapes to calculate their area. The tutorial provides examples of identifying rectangles, triangles, and trapezoids within complex figures and demonstrates how to sum their areas to find the total area of the composite figure.

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

• Calculate the perimeter of the figure.

• Use a formula for complex shapes.

• Break it down into known shapes.

• Estimate the area visually.

Which of the following shapes is NOT mentioned as a known shape for area calculation?

• Trapezoid

• Circle

• Rectangle

• Triangle

How many sides does the composite figure discussed initially have?

• Three

• Five

• Four

• Six

What is the formula for the area of a rectangle?

• Length x Width x Height

• 2 x (Length + Width)

• Length x Width

• Length + Width

What additional shape is formed when the rectangle is separated from the composite figure?

• Hexagon

• Triangle

• Square

• Circle

What is the formula for the area of a triangle?

• Base x Height

• 1/2 x Base x Height

• Base + Height

• Base x Height x 2

In the new composite figure, what shape replaces the triangle?

• Circle

• Square

• Trapezoid

• Pentagon

What is the formula for the area of a trapezoid?

• Base1 x Base2 x Height

• 1/2 x (Base1 + Base2)

• Height x (Base1 + Base2)

• 1/2 x Height x (Base1 + Base2)

What is the purpose of breaking down composite figures into known shapes?

• To make them look more complex.

• To create new shapes.

• To simplify the area calculation.

• To change their dimensions.

What should you do after calculating the areas of individual shapes in a composite figure?

• Multiply them together.

• Subtract them from each other.

• Add them together.

• Divide them by the number of shapes.
