First find the limits of integration.
From the graph, it looks like the limits are x=-9 and x=-2.

int%28%28-x%5E2-11x-18%29%2Cdx%29=-x%5E3%2F3-%2811%2F2%29x%5E2-18x%2BC
So then,

A=-%28-8%2B729%29%2F3-%2811%2F2%29%284-81%29-18%287%29
A=-721%2F3-%2811%2F2%29%28-77%29-126
A=-721%2F3%2B847%2F2-126
A=-1442%2F6%2B2541%2F6-756%2F6
A=343%2F6
