Answer:
303.6ft² or 347.88 ft²
Step-by-step explanation:
The question is on area
The dimensions of the living room are given as;
Length= L = 22'-0"
Width= W= 12' -0" or 13'- 9"
Area= L× W
22'×12'=264ft²
Allow 15% waste
264× 115/100 =303.6ft²
or
Length= 22' and width = 13' 9"
change 9" to ft ⇒1'=12"...........................divide by 12"
9/12=0.75'................add to 13'
13'+0.75'=13.75'
Area=L×W
22'×13.75'=302.5ft²
Add 15% allowed waste
302.5 × 115/100 =347.88 ft²
