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.

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.
