Knowing the ratio between the dimensions but not knowing either dimension exactly means, the dimensions are unknown factors of some value, x.
4x is one dimension and 7x the other dimension.

2%284x%2B7x%29=154
2%2811x%29=154
11x=77
x=77%2F11
x=7

THAT is the factor to use.
4%2A7 is one dimension and 7%2A7 is the other dimension.
