Quadrilateral is a closed convex polygon bounded by four sides. We have already seen that the quadrilaterals are classified according to the interior angles and the sides. Therefore, the names of the quadrilaterals vary according to their properties. Areas of rectangle, square, parallelograms can be found by the suitable formulas derived. If we are given a quadrilateral whose sides or angles are unequal, we can find the areas by splitting it into triangles which do not overlap.
Hence in this section let us see different methods of finding the areas of quadrilaterals.
