A rectangle has a a width of 9 inches the area is 648 inches what is the length of the rectangle
yuradex [85]
The formula for a rectangle is length*width=area. Since we know the area and the width, we plug it in to the formula, we get length*9=648. 
l*9=648 is equivalent to l=648/9. Now we solve <span>l=648/9 and get l=72. SO the width is 72 inches. </span>
