What is one way to find the area of a composite figure?

• Divide the total area by the number of shapes in the composite figure.

• Break it down into simpler shapes and calculate the area of each shape, then add up the areas of all the shapes.

• Multiply the length and width of each shape and add them up.

• Find the perimeter of each shape and add them up.
