Area of Composite Shapes: Missing Measurements

Put area skills into action with this composite-shape worksheet! Students will use labeled side lengths to find missing measurements, calculate the areas of smaller shapes, and add those areas together to find the total area of the composite figure. This process will give learners a clear way to break a complex shape into familiar parts and solve it step by step.

Well suited for third- and fourth-grade students, this worksheet will strengthen understanding of area while reinforcing measurement and problem-solving skills. By employing their critical thinking skills, students will practice decomposing geometric shapes to find the target measurement.
