Question

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomial.

Answer 1

`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`.
