Someone pls answer this question

Answer 1

`9^2-x^2` and
`x(9-x)+9(9-x)`

Explanation:

The area of the larger square is 9*9=9^2. The area of the smaller square inside of it is x*x=x^2. The area of the light shaded gray is therefore 9^2-x^2, which is also equivalent to x(9-x)+9(9-x). Hope this helps!
