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

`C.\ Perimeter = 48 * 18`

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
