For Circle,

                                                              Area = Pie * (Radius) ^2     note: Pie is equal to 3.142 or 22/7

For Trapezium,

                                                              Area = ½ * Height of trapezium * Sum of parallel sides

For Triangle,

                                                              Area = ½ * Base * Height

For Parallelogram,

                                                             Area = Base * Height

Basic shapes you may ever encounter.
