Answer:

8 feet.

Explanation:

Before remodeling:

width = 9 ft

Area = 108 ft²

$\boxed{length = (Area)/(width)}$

$=(108)/(9)\\\\= 12 \ ft$

After remodeling:

width = 9 ft

Area = 180 ft²

$length = (180)/(9)\\$

= 20 ft

length after remodeling = 20 ft

To find the length of the added portion, subtract the length of the living room before modeling from the length after remodeling.

length of the added portion = 20 - 12

= 8 ft
