Understanding Areas of Composite Figures

What is the first step in finding the area of composite figures?

• Guess the area based on the figure's appearance.

• Calculate the perimeter of the figure.

• Divide the figure into simpler shapes.

• Multiply the dimensions of the figure directly.

What is the purpose of dividing composite figures into simpler shapes?

• To make them easier to draw

• To increase the figure's complexity

• To calculate the perimeter more accurately

• To simplify the area calculation process

What formula is used to calculate the area of a triangle?

• Length x Width

• Base x Height

• Base x Height / 2

• 2 x (Base + Height)

How do you calculate the area of a rectangle?

• Length x Width

• 2 x (Length + Width)

• Length + Width

• Length x Width / 2

What is the correct formula for the area of a rectangle used in the examples?

• Length x Width

• 2 x (Length + Width)

• Length + Width

• Base x Height / 2

What is the total area of the first example figure?

• 31.5 square feet

• 21 square feet

• 42 square feet

• 10.5 square feet

Which of the following is not a step in calculating the area of composite figures?

• Calculating the volume of each simpler shape

• Adding the areas of simpler shapes together

• Calculating the area of each simpler shape

• Identifying simpler shapes within the figure

In the second example, what is the length used for the rectangle's area calculation?

• 20 feet

• 5 feet

• 10 feet

• 15 feet

How is the base of the triangle determined in the second example?

• By dividing the height by 2

• By using the total length of 15 feet

• By adding 5 to 10

• By subtracting 10 from 15

What is the total area of the composite figure in the second example?

• 10 square feet

• 60 square feet

• 50 square feet

• 40 square feet
