We can identify them by their vertices and slopes. Parallelogram are quadrilaterals with opposite sides parallel, but adjacent sides not perpendicular..The area of a rectangle is its length multiplied by its breadth. In the formula for the area of a parallelogram, the height is the perpendicular distance from about the areas of rectangles and triangles to find the areas of more complex shapes..

Before you can find the area of a regular quadrilateral, start by identifying the type of quadrilateral in the problem, since different types of quadrilaterals require different equations. For rectangles or rhombuses, simply multiply the base by the height to .Quadrilateral worksheets contain identifying types of quadrilaterals; charts and coloring activities; special focus in finding area and perimeter of parallelogram, t.zoid, rhombus, kite and quadrilaterals; finding unknown angles in parallelogram and quadrilateral; algebased questions and more..
