The formula for dimensions of a rectangle with a fixed area, say 5000, is:
5000 = h*w
Now, the domain of this function is all real numbers. For example, you could have h = 37.5 and w = 133 1/3. If you want all of the possible integer results, you will have to factor 5000:
5000 = 2*2*2*5*5*5*5
So, for any h and w which satisfy the original equation, h*w = 2^3 * 5^4. Every combination of these factors will yield an integer solution...
h = 2^0 * 5^0, w = 2^3 * 5^4
h = 2^1 * 5^0, w = 2^2 * 5^4
h = 2^2 * 5^0, w = 2^1 * 5^4
h = 2^3 * 5^0, w = 2^0 * 5^4
h = 2^0 * 5^1, w = 2^3 * 5^3
h = 2^1 * 5^1, w = 2^2 * 5^3
h = 2^2 * 5^1, w = 2^1 * 5^3
h = 2^3 * 5^1, w = 2^0 * 5^3
h = 2^0 * 5^2, w = 2^3 * 5^2
h = 2^1 * 5^2, w = 2^2 * 5^2
h = 2^2 * 5^2, w = 2^1 * 5^2
h = 2^3 * 5^2, w = 2^0 * 5^2
h = 2^0 * 5^3, w = 2^3 * 5^1
h = 2^1 * 5^3, w = 2^2 * 5^1
h = 2^2 * 5^3, w = 2^1 * 5^1
h = 2^3 * 5^3, w = 2^0 * 5^1
h = 2^0 * 5^4, w = 2^3 * 5^0
h = 2^1 * 5^4, w = 2^2 * 5^0
h = 2^2 * 5^4, w = 2^1 * 5^0
h = 2^3 * 5^4, w = 2^0 * 5^0

There is no formula
Simply take the one you have and do height 1, 2, 3, 4, 5, 6 and so on.
If you want integers on both sides, then you have to factor 5000 (in this case) to its integers - 1,2,5,10, 20, 50, 100, etc and use those.

Area = length x height. I'd say, list all the factors of 5000. For every set, you have one possible rectangle with that area.

You have to break down your area in primes and then choose.
Here 5000= 2^3 x 5^4 so you have 4x5 choices for one side and one choice for the other. By symmetry, that gives you only 10 solutions.

It would be a matter of finding all the pairs of numbers that are factors of 5000 .

we would choose to be responsive to the section A Rectangle a million tells us that A = ab Rectangle 2 tells us that A = (a-3)(b+2) Rectangle 3 tells us that A = (a+3)(b-a million) are you able to verify how we could use those to verify what we could be responsive to?
