# Finite and Infinite Areas Exercises

### Example 1

Exercise. Look at the picture below, which shows a region *A* within a region *B*.

If the area of region *A* is infinite, what does that tell us about the area of region *B*?

### Example 2

Exercise. Look at the picture below, which shows a region *A* within a region *B*.

If the area of region *B* is finite, what does that tell us about the area of region *A*?

### Example 3

Exercise. Look at the picture below, which shows a region *A* within a region *B*.

If the area of region *A* is finite, what does that tell us about the area of region *B*?

### Example 4

Exercise. Look at the picture below, which shows a region *A* within a region *B*.

If the area of region *B* is infinite, what does that tell us about the area of region *A*?
