Answer:

144

Explanation:

No. of square tiles needed = #a^2/b^2#

So, if #a=96# and #b=8#, then all you do is you have to sub into your 2 numbers into the equation

No. of square tiles needed = #96^2/8^2 = 144#

Answer:

#144# tiles are needed.

Explanation:

Area of floor is #96^2# square inches and

area of each tile is #8^2# square inches

Hence, number of tiles needed are

#(96xx96)/(8xx8)#

= #(cancel96^12xxcancel96^12)/(cancel8^1xxcancel8^1)#

= #12xx12#

= #144#
