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
