A rectangular floor is 7 yards long and 3 yards wide. what is the area of the floor in square feet? be sure to include the corre
mario62 [17]
There are a couple ways to do this, but basically you need to convert the units. 

<span>7 yards x 3 ft/yard = 21 feet </span>
<span>4 yards x 3 ft/yard = 12 feet </span>
<span>So the area (in sq. ft) will be: </span>
<span>21 x 12 </span>
<span>= 252 sq. ft. </span>

<span>Alternatively, you can figure the area in square *yards* and then multiply by 9 sq. ft per sq. yard. </span>
<span>7 yards x 4 yards x 9 sq. ft/sq. yard </span>
<span>= 252 sq. ft.

hope this helps :)</span>
