@aditya0788 it is okay for unordered but for ordered you have to count cases

assuming in 2nd question it is "product of 2 co-prime factors"

let 2 factors be X and Y

prime factorization of 11025 = 3^2 * 5^2 * 7^2 

now each power of prime number have 2 choices either X or Y

so , answer is 2^3 = 8 for unordered and 8/2 = 4 for ordered

Akhil has a board, similar to chessboard, except that it has only 6x6 squares. He calculated the number of rectangles (including squares) on the board. How many distinct values can the area of these rectangles assume? a) 72 b) 24 c) 36 d) 54 e)18

6*6 , 6*5 , .......... 1*1 = 21 

but 3 repetitions are there 

6*2 = 4*3 

3*2 = 6*1

4*1 = 2*2

so , 21 - 3 = 18

total cases = 4!

favorable cases = 1 

prob. 1/24
