Its as simple as length times breath there for it is 7/9 times 6/5 which has a common denominator of 45 so now it is 7/45 and 6/45 and then we say how many times did we multiply the denominator to get to 45 and use that number to multiply the numerator so now we have 35/45 and 54/45 and if you times both of them together you get 14/15 as a final answere
