Question

you ordered a desk that will fit the space, and also finished painting the walls and ceiling. now, you plan to place sound - reducing panels around the perimeter of the room to improve the acoustics of the space and reduce echo.
recall that the rooms dimensions are:
width: 12 ft.
length: 13 ft.
height: 8 ft.
whats the perimeter of the room?
50 ft.
156 ft.
25 ft.
33 ft.

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \(P\) of a rectangle is \(P = 2(l + w)\), where \(l\) is the length and \(w\) is the width. The height is not relevant for calculating the perimeter of the room's floor (which is a rectangle).

Step2: Substitute the values of length and width into the formula

Given \(l = 13\) ft and \(w=12\) ft. Then \(P = 2(13 + 12)\).
First, calculate the sum inside the parentheses: \(13+12 = 25\).
Then multiply by 2: \(P=2\times25\).
\(P = 50\) ft.

Answer:

50 ft.
