Answer:
5 parts are shaded and 4 parts are white so:
There are 9 parts all together.
We can then form ratio's of the white areas and the shaded areas:
White Area Ratio =
Shaded Area Ratio =
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:
5 times 5..........................
In the middle/Alike: 3,1,8,2,4
Outside for 318,274: Doesnt have 5
Outside for 138,524: Doesnt have 7
