Calculate area of the white region inside circle.
Area of the two white triangles in top left and bottom right:

Area of the two white quarter circles in the bottom left and top right:

Total area of unshaded white region inside circle:

Area of entire circle including the white and shaded regions

Area of shaded region is area of entire circle - area of unshaded white region

It’s not the same because if you simplify them there going to end up looking different (the answers) And they get a whole different do you denominator a numerator
Answer:
I am pretty sure it is dependent
Let me know if it is wrong.
Area= length(width)
1/5=1/3(length)
Length= 1/5(3/1) or 1/5 divided by 1/3
Length= 3/5 cm
Therefore, the length of the rectangle is 3/5 cm.
Hope this helps!
