since two aldehydes participate along with oh therefore the order of reaction is three

overall the reaction is a third-order reaction. It is second order wrt aldehyde and first order wrt base:-

rate = k[RCHO]2[OH] 

however at very high base concentration a second path (k'') becomes important and it becomes second order wrt base:-

rate = k[RCHO]2[OH-] + k''[RCHO]2[OH-]

for exams generally consider the first argument i.e. it is a third order reaction
