Answer:
Area of the square = [tex]x^2+2x+1[/tex]
Step-by-step explanation:
We need to find the area of the square
The side length of the square is (x+1)
Area of the square formula is (side)^2
Replace side with x+1
So the area of the square = [tex](x+1)^2[/tex]
[tex](x+1)^2= (x+1)(x+1)= x^2+x+x+1= x^2+2x+1[/tex]
Area of the square = [tex]x^2+2x+1[/tex]
