Since the hallway is a square, all the sides must be the same length, with each side being 6 feet long. Thus the area of the hallway is:
A=W*L
A= 6*6
A = 36 square feet
The carpenter charges $10 per square foot. So:
36(10)= $360
The customer has a coupon for $25 off, so subtract that from the total cost:
$360 - $25 = $335
The floor will cost $335.
