how to represent 97 on a rectangle? for 98 you have told to draw 49 columns and 2 rows. drawing 49 columns is a huge task but can we draw 14 columns and 7 rows? anyway for 97 which is prime number drawing 97 columns with one row is a huge task again. is there something like 100-3?
98 can be represented on rectangle as 14×7 as 14 and 7 are the factors of 98.
It is not necessary that the rectangle representation of the given number is unique.
But, the given number 97 is a prime number and it has no proper factors. So, it is not possible to represent it on a rectangle.
