Step-by-step explanation:
trigonometric fit:
when one side of a triangle is 3 and the other side of the triangle is 4, the big side is 5. so in this case, the dashed line means 3.
3 times 4 equals area of rectangle which is 12
3 times 4 divided by a 2 which is 6 is the half rectangle

Change the order of integration. The region over which you're integrating can be equivalently described by the set of points in the plane,
.
Then the integral becomes
