The video tutorial explains how to find the area of a polygon by dividing it into simpler shapes, specifically a rectangle and a triangle. The instructor demonstrates how to determine the dimensions of these shapes and calculate their areas. The rectangle's area is found using length times width, while the triangle's area is calculated using base times height divided by two. Finally, the areas are added together to find the total area of the polygon, emphasizing the importance of using square units for area measurement.

What is the first step in finding the area of a complex polygon?

• Find the longest side

• Calculate the perimeter

• Divide it into simpler shapes

• Measure the angles

Which two shapes are identified within the polygon?

• Circle and square

• Rectangle and triangle

• Trapezoid and parallelogram

• Hexagon and pentagon

What is a key property of a rectangle's sides?

• Adjacent sides are equal

• All angles are acute

• Opposite sides are equal

• All sides are equal

What is the length of the rectangle's side if the opposite side is 12 cm?

• 10 cm

• 12 cm

• 8 cm

• 6 cm

If the rectangle's width is 4 cm, what is the length of the other side?

• 12 cm

• 8 cm

• 4 cm

• 6 cm

How is the base of the triangle determined?

• By using the rectangle's side lengths

• By measuring the diagonal

• By measuring the height

• By calculating the area

What is the height of the triangle if the total height is 8 cm and the rectangle's height is 4 cm?

• 8 cm

• 6 cm

• 4 cm

• 2 cm

How do you calculate the area of a rectangle?

• Length plus width

• Length times width

• Sum of all sides

• Base times height divided by 2

What is the area of the rectangle if its length is 12 cm and width is 4 cm?

• 24 cm²

• 60 cm²

• 36 cm²

• 48 cm²

How is the area of a triangle calculated?

• Sum of all sides

• Length times width

• Base times height divided by 2

• Base times height
