Answer:
Multiplication
Step-by-step explanation:
This looks like the equation for the area of a rectangle.
Area = Lenght * Width
Given that the "l" variable and the "w" variable or next to each other without '/' or '\' , then we can safely say this a multiplication operation.
If there is no symbol between variables, it is assumed to be short-hand for multiplication instead of writing '*', '.', or 'x' in-between the variables.
