Answer:

[tex]\large\boxed{Width=x-12\ meters}[/tex]

Step-by-step explanation:

The formula of an area of a rectange:

[tex]A=wl[/tex]

w - width

l - length

We have:

[tex]A=x^2-144,\ l=x+12[/tex]

Substitute:

[tex]x^2-144=(x+12)(w)[/tex]

[tex]x^2-12^2=(x+12)w[/tex]           use a² - b² = (a - b)(a + b)

[tex](x-12)(x+12)=(x+12)w\Rightarrow x-12=w\to w=x-12[/tex]

Answer:

Width = x - 12 meters

Step-by-step explanation:

The rectangle has an area of x^2 - 144 square meters and a length of x + 12 meters.

Area = x^2 - 144

Length = x + 12

Formula: A = wl

Therfore, the expression that represents the width of the rectangle is Width = x - 12 meters.
