To tackle a similarity question, you would need to find a scale factor:
which is the multiplier to shrink or grow a measurement proportionately.

Therefore, to find the grow factor;

It’s AB/AE = 5/3

So our scale factor is 5/3

To find BC or AD, we need to grow the EF measurement as it is the smaller measurement of the corresponding side. So:

EF x 5/3 = AD
2 x 5/3 = 3.33333333333
So 3.3333333 is AD or BC

So we now have to find the area of both rectangle.

Rectangle AEFG = 3 x 2 = 6
Rectangle ABCD = 5 x 3.3333 = 16.6666

Ratio of yellow to blue is
Ratio of smaller to larger which is:

6 to 16.666666

After that we need to simplify the ratio, afterwards, we will get:

9 to 25

Hence the answer is
9:25
