13'0" x 22' 0". If the wall) 'thickness is 5 1/8", what are the inside dimensions of the living room?

12' 1" 3/4 x 21' 1" 3/4

Step-by-step explanation:

We simply have to calculate the interior dimensions.

We'll assume there's a wall all around the area, so to calculate the inner space, we have to subtract the wall's thickness from the given dimensions ... twice, since there's a wall at both ends of the width and both ends of the length.

Width: 13' - 5" 1/8 - 5" 1/8 = 13' - 10" 2/8 = 12' 1" 6/8 = 12' 1" 3/4

Length: 22' - 5" 1/8 - 5" 1/8 = 22' - 10" 2/8 = 21' 1" 6/8 = 21' 1" 3/4
