Mar 31, 2023 · You can decompose polygons into triangles and rectangles to find their area. The trapezoid shape can be divided into one rectangle and one right triangle. The rectangle is 6 meters by 3 meters, so the area is 6 × 3 = 18 m2.
Decomposing (or decomposition) is the process of dividing a geometric figures into smaller (non-overlapping) recognizable shapes. The general purpose of decomposing is to have shapes within the given figure that can be more easily manipulated for computations.
Decomposing shapes is the process of breaking particular shapes into other shapes. Given a large geometric shape, students are asked to break it up into smaller, known shapes. These large shapes can be known shapes themselves or simply abstract shapes.
