How many square feet of hardwood flooring are required for a living room floor, of L. 22'-0"x W. 12'-"W. x13'-9"? Allow 15% for waste

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
