Estimating perimeter and area of simple polygons

Knowledge about area, perimeter, plane geometry and polygonsBuild your intuition for the perimeter and area of simple polygons (polygons whose edges intersect only at vertices) by dragging the vertices of the polygon around the geoboard. To see a way of computing the area of simple polygons, see the Demonstration entitled Pick's TheoremComponente Curricular::Ensino Fundamental::Séries Finais::Matemátic
