Answer:

[tex]C.\ Perimeter = 48 * 18[/tex]

Step-by-step explanation:

Given

See attachment for her sketch

Required

Which equation do not represent the perimeter

From the attached sketch:

[tex]L =18in[/tex] --- Length

[tex]W =48in[/tex] --- Width

Perimeter (P) is calculated as:

[tex]P = 2 * (L + W)[/tex]

This gives:

[tex]P = 2 * (18 + 48)[/tex] ---- This represents (A)

Open bracket

[tex]P = 2 * 18 + 2*48[/tex] ---- This represents (B)

In algebra:

[tex]2 * a[/tex] means [tex]a+ a[/tex]

So, the expression becomes

[tex]P = 18 + 18 +48 + 48[/tex] --- This represents (D)

This implies that (C) does not represent the perimeter
