Given: 
Irregular Shape: 
Semi-circle and rectangle:
Area of a rectangle = l * w
Area of a semi-circle = (π r²)/2
Area of rectangle = 8 cm * 5 cm = 40cm²
Area of a semi-circle = (3.14 (4²))/2 = (3.14*16)/2 = 50.24/2 = 25.12cm²
4² is taken from diameter of 8cm divided by 2 to get the radius.
Total area = 40 cm² + 25.12 cm² = 65.12 cm²
        
             
        
        
        
Answer:
BE
Step-by-step explanation:
This is because it is the part of a line that has two endpoints and is finite in length.
 
        
                    
             
        
        
        
The answer is 6
h = 2 A/a+b = 2 51/10+7 = 6
        
             
        
        
        
Answer:
<u>The answer is B.</u>
Step-by-step explanation:
When you have three numbers in the left bubble, and 4 on the right for "mapping a," you cant have 2 going into one number on the right. You can only have 1 number going into 2 (shown in the mapping b image). 
<u>Thus, the answer will be "Mapping B."</u>
