Divide the area by the length to get the width



You can simplify it from there.

given:
A=%285x%5E2y%5E3%29%2F%284rs%29
L=%283xy%29%2Fr

What rational expression represents the width W
A=L%2AW
W=A%2FL....plug in given values

W=%28%285x%5E2y%5E3%29%2F%284rs%29%29%2F%28%283xy%29%2Fr%29

W=%28r%285x%5E2y%5E3%29%29%2F%28%284rs%29%283xy%29%29



W=%285xy%5E2%29%2F%284s%2A3%29

W=%285xy%5E2%29%2F%2812s%29
