Question 257223: Write an expression for the area of the shaded region of a square. the problem shows 2 squares 1 inside the other, with the outside square shaded in. The numbers on the smaller inside square is 4 and 4 and the outside square that is shaded in is x and x variables. I was thinking that the answer would be x²+ x². Is this soultion the right way?

The BIG area (square) has an area of x*x = x^2
The shaded region is the difference: x^2 - 16
