You can put this solution on YOUR website!
Convert the kitchen measurements to inches and find the total area of the kitchen.
12%2A12%2B8=144%2B8=152inches
17%2A12%2B9=204%2B9=213inches
A=152%2A213=32376sq.inches
Each tile has an area of
A%5Bt%5D=8%2A8=64sq. inches.
So then,
N=A%2FA%5Bt%5D=32376%2F64=505.9
Round up to N=509 but you should always purchase 10% more in case of mistakes or mismeasurement.
