One is negative 4 and one is positive 2
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35
minus original aera
which is 5 by 7 which is 35
4a²+24a+35-35=4a²+24a
3rd option I think, can't tell which is which
I believe the correct answer to your problem is C , you’re welcome
