Find the width of a rectangular patio with a length of 16 ft and an area of 200 square feet

So, the basic equation for the area of a parallelogram is this:

length * width = area

So let's represent the width, the unknown number, as w:

w * 16 = 200

Let's divide both sides by 16 to isolate w:

w = 12.5

The width is 12.5 feet
