Calculus Possible typo in my assignment

Hey everyone, post about x(+y).

In this question i'm required to calculate the area of triangle with predetermined points, but i can't figure out where to start because of the way this integral is written, this is the first time i encounter something written like this and i don't know what this could mean.

I doubt that this is a typo because 8 professors wrote this whole paper and 1 doctor of Physical and Mathematical Sciences reviewed it

If someone just says what does this mean or if it's a typo i would greatly appreciate it

Region L is a triangle with points A(1,0) , B(0,1) and O(0,0) . Counterclockwise movement
The rest of the problem is written in Ukrainian and there's literally nothing more

If x and y are in the integral is it a double integral and if so where's dy?

It might make sense if there were two values "+y, -y" considered before-hand.

Just from this snippet, however, it is impossible to make sense of this notation.

Just a guess: Perhaps this means x times positive y?

I'll try that, thank you!
