The formula for the area of a rectangle is l * w = a. So let's plug the values that we know in:
38w = 577.6. We can solve this equation by following these steps:
Divide each side by 38 to isolate the variable.
557.6 divided by 38 is 15.2.
We can check this by multiplying 15.2 by 38.
So the width is 15.2
