  1. Warm Up

  2. Area (and Perimeter) of Composite Figures Objective • Students find composite area of figures by decomposing the plane into familiar figures (triangles, quadrilaterals, circles and semi-circles). S4.C4.03 – Calculate the area and perimeter of composite 2-dimensional figures.

  3. Composite

  4. What information can we take from the image? What would we need to figure out the area or perimeters for these compound shapes? After calculating the areas (or perimeters), what is the next step, and how do you know?

  5. Then we start to see….

  6. And in real life….

  7. BUT…. Before we can jump straight to compound figures, we need to understand simple figures.

  8. Examples
