Answer:
28 Inches
Explanation:
10 ft x 12 = 120 inches
120/2 is 60 inches to the center of the wall
28+28+8 = 64 in measure of the frames and the space between them
64 / 2 = 32 in measure from center of both paintings and the 8 in requirement
60 in - 32 in = 28 in is the measurement from the wall to the outer diameter of the paintings
