1)Composite numbers are numbers that have more than two factors
For eg. 6=2x3x1 is a composite number as it has more two factor
2)rational numbers are number that are in form of p/q such that p and q are integers and q is not equal to 0. Irrational nos are opposite of natural number
Eg. 4/3 is a rational number
Root of 2 is a irrational number
3)area= 9x9=81 cm
Perimeter =9x4=36
4)area=lxb=30
Length=6
Breadth=30/6=5
5)area=1/2bh
1/2x10xh=50
Height=10cm
6)999
7)1000
