Answer:
80 units squared
Step-by-step explanation:
well first you get the area of the big rectangle, 8x12=96
then you need to get the area of the light sqaure, because there is the same amount of ticks 3 times, the equal lengths are 12/3= 4 units each so the dimensions of the sqaure are 4 by 4 4x4=16 then you do 96-16= 80 units squared.
