The figure above shows a rectangle ABCD and a quarter of a circle with a radius of 6. If the area
of region I is equal to the area of region II, what
is the value of x, the length of AB?
(A) 3
(D) 271
(E) 4.571
(B) 7
(C) 1.57

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:
