Let the area of sqaure be equated to x, which means let the entire area of the square equal to x:
x = Area of whole square
Now we can form an equation :

So now we just need to solve for x:


The area of the square is:

Answer:
C) $25 + $1.25
Step-by-step explanation:
1. 51 x .5 = 25.5
2. 25.5 x .05 = 1.275
