Answer:
[tex]A=(x+4)^2\text{ or } A=x^2+8x+16[/tex]
Step-by-step explanation:
We have a square garden. One side of the garden has a length of (x + 4).
And we want to write an expression that could represent the area of the garden.
Remember that for a square, all sides have equivalent lengths. So, every side measures (x + 4). The area of a square is given by:
[tex]A=s^2[/tex]
Where s is the length of one side.
Substitute:
[tex]A=(x+4)^2[/tex]
Expand if desired. Hence, the expression for the area is:
[tex]A=x^2+8x+16[/tex]
