A. 2x^2(75-8Π)
B.150x^2-4Πx^2)
C.134Πx^2
D.134x^2
My answer is A

Please correct me if I'm wrong.

Im basically suppose to Find the area of the rectangle. Find the area of the circle. Subtract the area of the circle from the area of the rectangle. I'm guessing D

Zeest · Answer

The answer should be D..... because for finding out the remainig area you'll have to minus the area of circle from area of rectangle i.e ((10x)×(15x)) minus (pi×(4x)^2) This will give you D.

D is wrong. It is not B, nor C. Duh. 15x*10x-PI*(4x)^2 2x^2(75-8PI)
