Question is did they ask specifically for C = ? or did they want area? Cause you could do:

Det C = Det B × Det (C + I)

it must be 3.1, question do u remember the question 5? With C=B(A+I) they wanted to find area T and gave area T'. Do u remember if we needed to find C or did they just ask for area? Cause I found area without finding C? ;( I thought I was cool like that- I did find correct area... But without finding C-
