Answer:


A=(x^2+16+8x)\ \text{inches}^2

Explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :


A=\text{side}^2

So,


A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2

So, the area of the square is
(x^2+16+8x)\ \text{inches}^2.
