Question 1204196
<pre>
Here's the picture. The large 9x6 rectangle has 54 little squares (square
centimeters of area) and the little 4x4 square outlined in red has 4x4 = 16
little squares (square centimeters of area). 

Notice that we took 5 cm off the length and 2 cm off the width (or height)
to have just that 4x4 square.
