7-82.

Given the equations of the riverbanks, determine the area of the land. Homework Help ✎

**North Bank:**

**South Bank:**

The *x*-axis is the line pointing east, and the *y*-axis is the line pointing north.

Set up an integral to find the area of the Northern region first.

Note that this will be the area between a horizontal line (on top) and a curvy line (on the bottom).

The area of the Southern region will be easier to set up.
