Answer:

5 inches

Explanation:

Area is just length time width (how wide it is). Since we have two values, we can make an equation to solve for the variable. Because we're trying to find width, we'll use "w" as the variable for this equation.

The equation can be seen as A=l*w, and if we substitute A and l, we can make the equation:

25=5*w, or 25=5w

Since w is multiplied to 5, and we need to isolate w, we have to do the inverse (divide) both sides.

25/5=5

5w/5=w

From this, we get w=5

I hope this helped!
