Answer:
9 * l = 54
Step-by-step explanation:
You don't need to worry because you are not the smartest, everyone are different, some concepts might be difficult, but will become easy soon....
Here is the answer to your question, 
area of a rectangle = length * width
( * = multiplication symbol, specifying as many feel confused )
A = l * w

9 * l = 54
