A total of 2 rectangles each have a length of $L$ and a width of $W$ . A total of 3 circles each have a radius of $R$ . The sum of the perimeters (circumferences) of all these rectangles and circles is 150. Which equation represents this situation?

A.

$2 (L + W) + 3 (2 π R) = 150$

B.

$4 (L + W) + 6 π R = 150$

C.

$2 L W + 3 π R^{2} = 150$

D.

$2 L + 2 W + 2 π R = 150$
