Measurement Price Calculator

hi,

with the measurement price calculator plugin, the customer now would be able to only pay for the total sqm, based on the input in length x width.

the challenge is that we have 2 different shipping methods:
1- max 2m length x 70cm we can ship with GLS, which the customer pays 24,99 for
2- above the mentioned size in 1, we organize the delivery with more complex logistics and the customers pays 70 for this method

how can we set a rule that the shipping method auto applies based on his input in length x width?
