you know one side is 1.1w (w representing the unknown side) and the area is 3.3w squared. now you need to plug in the numbers you know into your formula which would look like this: 3.3w squared is equal to 1.1w times w. now you need to solve for w by multiplying 1.1w and w to get 1.1w squared. now you are going to divide 1.1 w squared on both sides which gives you w equals 3
The simplified answer would be 2 1/16. To get to that answer, first you would multiply 1/2 by 8 to get to 8/16. then, you would add 1 9/16 with 8/16 to get 1 17/16. As I said before, the simplified answer would be 2 1/16.
