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 2*0 + 1 = 1
1st odd number = 3 2*1 + 1 = 3
2nd odd number = 5 2*2 + 1 = 5
3rd odd number = 7 2*3 + 1 = 7
4th odd number = 9 2*4 + 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
