Hi!
Answer:
A) 331.24
Step-by-step explanation:
To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.
I hope this helps! :)
 
        
                    
             
        
        
        
Answer:
c= ab + d/ a
Step-by-step explanation:
Let's solve for c.
a(c-b)=d
Step 1: Add ab to both sides.
-ab + ac + ab = d+ ab
ac = ab + d
Step 2: Divide both sides by a.
ac / a = ab + d / a
c = ab + d/ a
Answer:
c= ab + d/ a
