32 ft^2
Step-by-step explanation:
First you need to find out the area of Annie's floor which is 7 x 7 which the product is 49. Next, it says that Davids floor is 2ft larger than the length and width of Annie's floor. So in that case u have to add 2 to 7 to get 9 as the lenght and width for Davids floor. And 9 x 9 is 81 correct? So then to find the difference subtract 49 from 81 to get 32.
