Parameterize by the vector function
so that the normal vector to is given by
with magnitude
In this case, the normal vector is
with magnitude . The integral of over is then
where is the region in the plane over which is defined. In this case, it's the triangle in the plane which we can capture with and , so that we have
x= 15/2 im pretty sure
