Painting an irregular figure can be tricky if we don't know the exact area. This interactive presentation reveals that irregular figures can be broken into smaller, simple figures that use the area formulas. Go through two examples, including triangles, squares, and rectangles, to find the area of the whole figure. Practice more examples with the additional practice problems and test your learners' skills to see if they can recognize how to break apart the shapes.
