MA.6.GR.2.2 · Geometric Reasoning
Students solve mathematical and real-world problems involving the area of quadrilaterals and composite figures by decomposing them into triangles and rectangles. They find areas of parallelograms, trapezoids, and irregular shapes, and they work backward to find a missing side length when the area is given.
FAST items show labeled diagrams of quadrilaterals and composite shapes with equation editor answers for the area, plus multiple choice items finding missing dimensions from a known area.
