Question

Mary wants to apply a strip of wallpaper along the walls just below the ceiling. If the room is a 14 ft by 12 ft rectangle, then the strip of wallpaper needs to be at least how long?

Answer 1

Answer:

52 ft.

Step-by-step explanation:

In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.

So, rectangles has opposite sides equal, therefore, the perimeter should be:

$P=2 (L+l)$; having L as the larger side.

$P=2(14+12)\\P=2(26)\\P=52$

Hence, the strip of wallpaper needs to be as least 52 ft.
