Essential Ideas• A composite figure is a figure that is formed by
combining different shapes.• The area of a composite figure is determined by
dividing the figure into familiar shapes and using the area formulas associated with those shapes.
• The rectangle method can be used to determine the area of composite figures on the coordinate plane.
• The Pythagorean Theorem is used to determine the perimeter of composite figures on the coordinate plane.
