In this worksheet, kids will practice the area of polygons by following three steps. First, they need to find and label the missing lengths on each polygon. Second, they need to decompose the shape into simpler shapes, such as rectangles and triangles. Finally, they need to find the area of the simpler shapes and add them together to get the area of the polygon.

Teaching the area of a polygon by decomposing the shape is like breaking down a larger shape into smaller, more manageable pieces. It's like having a large sandwich you can't eat all at once, so you cut it into smaller pieces you can handle. We might break a complex shape into squares, rectangles, or triangles, and finding the area of these simpler shapes is easier. Then, we combine all the areas to find the complex shape's total area.
