Calculating Area and Dimensions

The video tutorial explains how to find the area of a polygon by first determining the lengths of missing sides. It involves calculating the missing side on the right and the top side of the polygon. The area is then calculated by dividing the polygon into two rectangles: a 9 by 8 rectangle and a 3 by 3 square. The total area is found by adding the areas of these two shapes, resulting in 81 square units.

What is the length of the missing side on the right of the polygon?

• 12 units

• 3 units

• 5 units

• 8 units

How do you find the length of the top side of the polygon?

• Multiply the lengths of the bottom and another side

• Add the lengths of the bottom and another side

• Subtract the length of the bottom from the total length

• Subtract the length of another side from the bottom

Into how many rectangles is the polygon divided to calculate the area?

• One

• Four

• Three

• Two

What is the area of the 9 by 8 rectangle?

• 72 square units

• 36 square units

• 81 square units

• 27 square units

What is the total area of the polygon?

• 81 square units

• 63 square units

• 72 square units

• 90 square units
