Conditional statement for ladybug sunlight hours

Hi everyone.
i am using sunlight hours component for a specific period analyse and I should get “the average number of daily hours which at least 2sqm of floor area receive direct light” from the result.I dont know which component should i use to make this conditional statement. I used the LD mesh threshold selector but i couldnt give it the area.
I appreciate if anyone can help me.
