However by looking at a number it is not easy to figure out whether a number is prime or composite. Every even number excpet 2 is a composite number so, any number having last digit as 0, 2, 4, 6 or 8 is a composite number. This is one of the ways to figure out. However for the odd numbers it becomes diificult to figure out. For a quicker analysis there are divisiblity rules. These are shorthand ways to find whether a number is divisble by another without performing actual division. Please take a look at the related links(below) for more information.

A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.
