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 =


(4)/(9)

Shaded Area Ratio =


(5)/(9)

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 :


(5)/(9) x = 165

So now we just need to solve for x:


x = (165)/( (5)/(9) )


x = 297

The area of the square is:


297 {cm}^(2)
