Answer:

Explanation:
The formula to find the area of a rectangle is:
×
, where
is width and
is length.
So, if we know the area
and the length
, we can find the width with the formula

You can get this answer by using the definition of area, which is the first equation, and isolating
.
Remember, when we want to move a factor to the other side of the equality, 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
