Which formula to use with multiple criterias?

I have been trying to use AVERAGEIFS formula to find a range of prices for my data but have failed to solve it.
The data is as follows

I want to find out the average prices of 32 inch (In the actual sheet there are multiple sizes e.g 30,34,40, etc) that is GM Type but including ones that are labeled GM 2K and GM 4K. Which formula should be used? I am a beginner in Excel FYI.
