The angle is 100 degrees which is 10 degrees more than a
right angle. The formula for area is ,
where is any of the sides, and once you've
chosen that side for a base, then you find the height,
I'll choose the side = for a base. The angle, degrees
is between this base and the side that =
I'll drop a vertical from the end of the side = , and that
will be my height
Have you had trig, or is this a trig question?
If so,

It looks like the 1st answer is correct
