The area of a rectangular piece of paper is 1/2 square foot

Answer:

The area of a rectangle is the product of length and width. We can solve this formula to find the width:
A = LW
W = A÷L . . . . . . divide both sides of the equation by L

For the given area and length, this looks like ...
[tex]W=\boxed{\dfrac{1}{2}\div\dfrac{2}{3}}[/tex]
