Jesse's room is 19 feet wide and 20 feet long. How much longer is her room than it is wide?
First, we need to find the width of Jesse's room in feet. 19 feet is the same as 19/1 feet, so we can say that the width of Jesse's room is 19/1 feet. 

Next, we need to find the length of Jesse's room in feet. 20 feet is the same as 20/1 feet, so we can say that the length of Jesse's room is 20/1 feet. 

Now, we need to find the difference between the length of the room and the width of the room. The length of the room is 20/1 feet and the width of the room is 19/1 feet, so the difference is 1/1 feet. 

We can simplify 1/1 feet to just 1 foot, so we can say that the room is 1 foot longer than it is wide.

Therefore the answer (numeric) is:
