Question

Can someone please help me with this? Show work please.

Answer 1

8 feet.

Explanation:

Area of rectangle:

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
