First find the area of the blue notebook by using the formula A=bh
A= 20×30 = 600 cm squared
Now find the area of the stickers using the same formula.
A=bh
A= 2 × 2 = 4 cm squared
Since there are 7 stickers then 4×7 = 28 cm squared is the area of all of them added together. Now simply subtract the area of the stickers from the area of the notebook to find how much of the notebook is still showing.
600 - 28 = 572 cm squared
