Answer: 128.86cm²
Step-by-step explanation:
The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.
Area of the rectangle                                  =  11 x 12 
                                                                      =  132cm²
Area of the circle with radius of 1cm          =  πr²
                                                                      = 3.142 x 1²
                                                                      = 3.142cm²
Therefore , area of the shaded  region      = 132cm²  -  3.142cm²
                                                                     = 128.86cm²
 
        
                    
             
        
        
        
Answer: A.
The reason is because if you're adding a negative to a number, it's subtraction, which is in the expression.

PEMDAS. parenthesis, exponents, multiple or divide (whichever come first from left to right), add or subtract (whichever comes first from left to right)
So first do stuff in parenthesis.
Then do divide because thats next on the list and it happens earlier than the multiply one.
So, A
        
             
        
        
        
87 is greater than 13.688
