how many different rectangle each of 72 sq mtr area can be formed keeping the measurments of length as well as breadth in whole number of centimetrs.

• Given area of rectangle 72 sq mtr
  but asking the area in cms. so, area= 7200 sq cms
  area of rectangle is l*b
  the no of factors of 7200 is 54
  so the two rcycled combinations of length and breadth is 54/2 = 27
  27 different rectangles are formed in whole num of cms

• (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

• 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....
