Hi, there--
.
The piece of cloth is a rectangle so we use the formula, A=L*W, to find the area. L is the length and W is the width.
.
We are given the width (2 feet) and the area (18 square feet). We need to rearrange our formula to solve for L.
.
A=L%2AW
.
L=A%2FW
.
Substitute the known dimensions into the formula.
L=18%2F2
.
Simplify.
L=9
.
The equation L=9 means that the fabric is 9 feet long. That makes sense if you think about it because 2*9=18.
.
Hope this helps. Feel free to email me via my gmail account if you have questions about the solution.
