Example :side (a) = 4 Area of square = 4 * 4 = 16Area Of Rectangle :The measure of total space occupied by a rectangle.Example :side a = 5 side b = 8 Area of rectangle= a * b = 5 * 8 = 40Area Of Parallelogram :Total space of the parallelogramExample :base (b) = 7 height (h) = 3 Area of Parallelogram = b * h = 7 * 3 = 21

Area Of Trapezoid :The total space covered by the trapezoid.Example :base b1 = 6 base b2 = 4 height h = 3 Area of Trapezoid = (b1 + b2) * h / 2 = (6 + 4) * 3 / 2 = 10 * 3 / 2 = 30 / 2 = 15Area Of Circle :Measure of the area enclosed by a circle.Example :radius of circle (r) = 7 Area of circle =π (r * r) = (22/7) (7 * 7) = 22 * 7 = 154Axis (graph) :A reference line to draw a graph in x, y axesExample :

Axis Of Symmetry :Axis of symmetry is a line that divides anobject into half and creates mirror images of each other. This line is always vertical.Example :Base (geometry) :Bottom line of a shape or bottom face of a solid object.Example :Bar Graph :Bar graph is a pictorial representation of any statistics which is used tocompare data. It shows quantity or numbers in the form of bars whichcan be either horizontal or vertical.Example :

Binary Number System :A binary number system is also called as base-2 number system. This system uses only 0s and 1s to represent letters, numbers and other characters and it is used by almost all modern computers.
