3.6(D)Cut a Shape to Find Its Area
Decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area.
Part of The student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties
