Here's a graph of it: https://www.desmos.com/calculator/uhp2jndcg1

OpenStudy (igreen):

We can pretend it's a rectangle with side lengths of 11 and 8. The area of a rectangle is \(A = lw\), so multiply 11 * 8 @smartkid2000

OpenStudy (anonymous):

88

OpenStudy (igreen):

Yes, now we have to find the area of the triangle in the top right and subtract that from 88.

OpenStudy (igreen):

It's a right triangle. \(A = \dfrac{ab}{2}\) a measures 5 units, and b measures 8 units. Multiply 8 * 5 and divide by 2. @smartkid2000

OpenStudy (anonymous):

20

OpenStudy (igreen):

Yes, now subtract 88 - 20.
