(1,72),(2,36),(3,24),(4,18),(6,12),(8,9)..so 6 rectangles

the ans given by banti is correct but.. there is a thing... (L,B) eg (1,72) can be (72,1).. the length and breadth can get exchanged....
therefore, the answer will be.....
(1,72),(72,1),(2,36),(36,2),....so on therefore answer is 12.

1 sq. meter= 10000sq cm
area=720000 sq cm
factoroisation of 720000 gives 2^7*3^2*5^4
total factors are= (7+1)*(2+1)*(4+1)
= 8*3*5
=120

(1,72)(2,36)(3,24)(4,18)(6,12)(8,9)

area of rectangle 72 sq mtr
so, area= 7200 sq cms
area of rectangle is l*b
the no of factors of 7200 is 54
combinations of length and breadth is 54/2 = 27
like (1,7200)(2,3600)(3,2400).... like this to 27 terms....
27 different rectangles are formed
