A; Each part of the figure has an unequal area, because each part is a different size
Here, we want to select the best sentence that describes the area of the parts of the figure
We consider the validity of each of the statements
We have to match equality and different
If each part is same size, area will be equal
If each part is different size, area will be unequal
Looking at the option set, the best statement is between the first and last option
Now, looking at the quadilateral, the angle at the edges is 90 degrees
What this means is that we have a hypotenuse which is the measure of the side of the inner shape
That means each part of the figure has an unequal area, because each part is a different size
