Area of Composite Figures (Day 2)

50 Minute Class, Curriculum, Geometry

Learning Goal: Develop understanding of how to find areas of regular polygons, especially when only given the apothem, and also continue to practice with composite figures.



  • Common Core
    • 6.G.A.1 – Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
  • TEKS
    • G.11(A) – apply the formula for the area of regular polygons to solve problems using appropriate units of measure
    • G.11(B) – determine the area of composite two-dimensional figures comprised of a combination of triangles, parallelograms, trapezoids, kites, regular polygons, or sectors of circles to solve problems using appropriate units of measure
