The answer is C)48 square cm , because to find the area of 1 rectangle you have to first multiply 5x2=10 which there are 4 rectangles so you multiply 10 by 4 which gives you 40, next you look at the small squares the lines show that the each side equivalent so to find the area you do 2x2 which gives you 4 and if you have 2 squares it will give you 8 then you add that to the 40 from the rectangles which gives you 48. I hope this helped :))
