Hello, I think I can help you with this.
this formula is used when calculating perimeter( Line or set of lines that form the outline of a surface or figure)of a rectangle
let´s see this example
if we have a rectangle with length(L)=10 m and width(W)=5 m,the perimeter will be
P=2L+2W
P=2(10 m)+2(5 m)
P=20 m+10m
P=30 m
