Recap: Composite Shapes

Part of the Polygons & Quadrilaterals section of Coddy's Geometry journey. Lesson 51 of 61.

Challenge

Rectangle ABCD has AB = 10 and BC = 6. A corner triangle ECF is cut off along EF, with E on DC so that DE = 6, and CF = 2. Find the area of the piece ABFED that is left, then press Check.
