The answer is astronomer Galileo Galilei
The question would have been clearer if it had stated
A(L)=5L
according to standard math notation indicating that L is an independent variable. 5 is a numeric value, and therefore cannot vary, therefore a constant.
A constant of proportionality k when used in a proportional relationship, written
F(x)=kx
means that the function is proportional to the value of the independent variable x.
In the given case,
A(l)=5l, so 5 takes the place of, or simply IS, the constant of proportionality.
Note that the lowercase L in the above equation may have been, or could have been, confused with the numeric digit one (1). I usually write in uppercase when the letter L is used as a variable to avoid this problem.
It was a kind of social protest - people did not want to be discriminated because of their race or sex. This event was a precedence - nobody thought that something like this protest could occur at that time. Rosa Parks did something that made people think about tolerance and also made other people join her protest in different places.
