8.11 - Composite Figures
 Number and Number Sense, Computation and Estimation Measurement and Geometry Probability, Statistics, Patterns, Functions, and Algebra SOL Review Materials Frequently Asked Questions
 Geometry Focus: Problem Solving with 2- and 3-Dimensional Figures The student will solve practical area and perimeter problems involving composite plane figures. HCPS Course 3 Curriculum Guide
 Essential Knowledge and Skills Subdivide a figure into triangles, rectangles, squares, trapezoids and semicircles. Estimate the area of subdivisions and combine to determine the area of the composite figure. Use the attributes of the subdivisions to determine the perimeter and circumference of a figure. Apply perimeter, circumference and area formulas to solve practical problems. Essential Understandings How does knowing the areas of polygons assist in calculating the areas of composite figures? The area of a composite figure can be found by subdividing the figure into triangles, rectangles, squares, trapezoids and semi-circles, calculating their areas, and adding the areas together.
