If we can change this number without changing the ration we need to multiply both the numerator and the denominator by the same number. For instance, if we have the following ratio:

We can multiply both the numerator and denominator, say, by 7. Then:

As you can see, the ratio's number has changed but without changing the ratio itself because:

Answer:
306mm²
