How do we find the area of a octagon (side lengths are not correct)

The video tutorial covers the properties of a regular octagon, including equal sides and angles. It explains methods to calculate the area of various shapes like parallelograms, triangles, circles, and trapezoids. The tutorial then focuses on the formula for finding the area of a regular pentagon using the apothem and perimeter. An example calculation is provided, demonstrating the process and emphasizing the importance of units, specifically inches squared.

What defines a regular octagon?

• All sides are equal, but angles are different.

• All sides and angles are equal.

• Only opposite sides are equal.

• Only adjacent angles are equal.

Which of the following shapes' area calculation was NOT mentioned in the video?

• Parallelogram

• Hexagon

• Circle

• Triangle

What is the formula for the area of a regular polygon?

• Area = base x height

• Area = side x side

• Area = 1/3 x base x height

• Area = 1/2 x apothem x perimeter

How do you calculate the perimeter of a regular octagon with side length 15?

• Multiply 15 by 4

• Multiply 15 by 8

• Add 15 eight times

• Add 15 four times

What is the final unit for the area of the octagon calculated in the video?

• Cubic inches

• Inches
