We are asked to find the area of the following figure:
We notice that the figure consist of a large rectangle in the bottom part, and a smaller square of 5 in x 5 in at the top right. We find each area and then add them together for the total area:
Area rectangle = 18 in x 17 in = 306 in^2
Area of square 5 in x 5 in = 25 in^2
The addition of both gives: (306 + 25 ) in^2 = 331 in^2
So, please type as solution: 331 square inches.
