Question 92764
<pre><font size = 4><b>
A.how many 12 inch square tiles would be necessary to cover the floor of a
square room that measures 14 feet on a side?

A 12 inch square tile is 1 foot on a side so here is the picture of one
12 inch square tile:

          {{{drawing(200/14,200/14,0,1,0,1, rectangle(0,0,1,1) )}}}

Here is the picture of the square room 14 feet on a side.

          {{{drawing(200,200,0,14,0,14,
line(0,0,14,0), line(0,1,14,1), line(0,2,14,2), line(0,3,14,3), line(0,4,14,4), line(0,5,14,5), line(0,6,14,6), line(0,7,14,7), line(0,8,14,8), line(0,9,14,9), line(0,10,14,10), line(0,11,14,11), line(0,12,14,12), line(0,13,14,13), line(0,14,14,14), line(0,0,0,14), line(1,0,1,14), line(2,0,2,14), line(3,0,3,14), line(4,0,4,14), line(5,0,5,14), line(6,0,6,14), line(7,0,7,14), line(8,0,8,14), line(9,0,9,14), line(10,0,10,14), line(11,0,11,14), line(12,0,12,14), line(13,0,13,14), line(14,0,14,14) )}}}

Count them and you'll find there are 196 of them.

But an easier way to get 196 is to multiply 14 by 14.
