A composite figure is...

• A figure that is made up of more than one regular shape such as triangles, circles, rectangles, and trapezoids.

• A 3-dimensional figure that must be flattened to find the area.

• A figure often used in essays and musical compositions.

• A shape or drawing that a 2 year old would draw.

To find the area of a composite figure, you must...

• divide the figure into regular shapes that have area formulas and solve for their areas. Then you must find the sum of all of the areas.

• use the formula of the shape that looks most like the composite figure.

• close your eyes and randomly type in numbers in your calculator and hope for the best.

• multiply the base by 3.14 and square the height.
