1.) Perimeter of rectangle with base B and Height H.

Perimeter =  2(Base + Height)
 
               =  2(B + H)

2.) Nth odd number.
Odd number sequence = 1, 3, 5, 7, 9, 11, ........
                                                             (2n + 1)
zeroth, 0th, odd number = 1                    20 + 1 = 1    
1st odd number = 3                                21 + 1 = 3
2nd odd number = 5                               22 + 1 = 5
3rd odd number = 7                                23 + 1 = 7
4th odd number = 9                                24 + 1 = 9

And so on.   So the nth odd number starting from 0 is  = 2n + 1.
                  
3.) Area of triangle with Base B and Height H

    Area = (1/2)B*H  = (1/2)BH
