Answer

Clearly, the area should be smaller if we choose to use yards instead of inches.

Work Step by Step

96 in * 1 yd/36 inches = 2.6 yards 72 in * 1 yd/36 inches = 2 yards Thus, the area is 2*2.6=5.2 yards. Clearly, the area should be smaller if we choose to use yards instead of inches as our units. Note that while the numerical value will be smaller with yards, the actual area is the same, for changing units does not change the value of something.
