How to write a array


Well if I understand correctly, you are talking about an array of numbers. This is often written as an m x n array, where the array has m rows and n columns. So if you write "array, m = 6, n = 5" it would always be taken as an array of 6 rows and 5 columns.

Perimeter of a rectangle


1 tile by 20 tiles - perimeter of 1+ 20 +1 + 20 = 42
2 tiles by 10 tiles - perimeter of 2 + 10 + 2 + 10 = 24
(can't make a rectangle with 3 rows)
4 tiles by 5 tiles - perimeter of 4 + 5 + 4 + 5 = 18
5 tiles by 4 tiles - perimeter of 5 + 4 + 5 + 4 = 18
(can't make a rectangle with 6, 7, 8 or 9 rows)
10 tiles by 2 tiles - perimeter of 10 + 2 + 10 + 2 = 24
20 tiles by 1 tile - perimeter of 20 + 1 + 20 + 1 = 42

So 6 different rectangles. Smallest perimeter is 18.

Whats prime numbers


Prime numbers are those numbers (greater than 1) that cannot be divided by any number except themselves and one.
The Greek Eratosthenes created a method to find out these prime numbers, although it only worked over a limited range:
1) Write out the numbers from 1 to 100 in ten rows of 10.

hundsq.gif2) Cross off number 1, because all primes are greater than 1.
3) Number 2 is a prime, so we can keep it, but we need to cross off the multiples of 2 (i.e. even numbers).
4) Number 3 is also a prime, so again we keep it and cross off the multiples of 3.
5) The next number left is 5 (because four has been crossed off), so we keep it and cross of the multiples of this number.
6) The final number left in the first row is number 7, so cross off its multiples.
7) You have finished. All of the "surviving" numbers (coloured in white below) on your grid are prime numbers.

If i am not mistaken you are saying the price was reduced by 20% per room hence here is the answers to your question.

Initially 24 rooms were rented at 28,800 for a total of 691200
AFTER THE 20% discount

You were already able to rent 30 rooms at 23040 for a total of 691200 hence you were able to rent 6 more rooms after the 20% discount
