Question

Lindsay will lay a certain number of 18in. square tiles in a line to form a walkway. Which of the following is NOT a possible length for the walkway if she uses only whole tiles? (a) 6ft (b)10ft 6in (c)32ft

Answer 1

32 ft is not a possible length for the walkway because if you divide 32 ft(which is also 384 in.) by 18, you do not get a whole number.
