Answer:
[tex]w=\frac{A}{l}[/tex]
Step-by-step explanation:
The formula to find the area of a rectangle is: [tex]A=w \times l[/tex], where [tex]w[/tex] is width and [tex]l[/tex] is length.
So, if we knoe the area [tex]A[/tex] and the length [tex]l[/tex], we can find the width with the formula
[tex]w=\frac{A}{l}[/tex]
You can get this answer by using the defintion of area, which is the first equation, and isolating [tex]w[/tex].
Remember, when we want to move a factor to the other side of the equalty, we must pass it with the opposite operation. So, in this case, width was multiplying, and it passed to the other side dividing.
Therefore, the answer here is [tex]w=\frac{A}{l}[/tex]
