Question

Hailey wants to put a skirt around her desk to hide all her computer equipment and cords. She measured her desk, found the dimensions, and drew the sketch below.

Answer 1

Answer:

$C.\ Perimeter = 48 * 18$

Step-by-step explanation:

Given

See attachment for her sketch

Required

Which equation do not represent the perimeter

From the attached sketch:

$L =18in$ --- Length

$W =48in$ --- Width

Perimeter (P) is calculated as:

$P = 2 * (L + W)$

This gives:

$P = 2 * (18 + 48)$ ---- This represents (A)

Open bracket

$P = 2 * 18 + 2*48$ ---- This represents (B)

In algebra:

$2 * a$ means $a+ a$

So, the expression becomes

$P = 18 + 18 +48 + 48$ --- This represents (D)

This implies that (C) does not represent the perimeter
