Without any numbers this is hard to calulate
        
             
        
        
        
I think it will be 22 minus 6/5+3 (5+3=8)
        
             
        
        
        
Answer:
21.5 square m
Step-by-step explanation:
You find the area of the shaded space by finding the area of the square and the removing the area of the circle.
The area for the square is 10x10=100.
All you have to do is follow the formula, (3.14)r^2. However, the 10 is NOT the diameter! The radius is half of the diameter. So, it's 3.14x5x5, which is 3.14x25=78.5.
Then, you can do 100-78.5=21.5
 
        
             
        
        
        
If you times it by 100 you would have to move the decimal point right two steps.
If you multiply a decimal with 10 you would move the decimal point once to the right. if you had 1000 you would have to move the decimal point three times to the right because there are three zeros.
Hope this was helpful.
