The average bedroom in an apartment is approximately 16’x10’ with an eight foot ceiling. As an interior decorator that loves the 1970’s decor, you need to cover the walls with groovy flowered wallpaper. If one roll of wallpaper covers 50 ft^2, then determine how many rolls of groovy flowered wallpaper is needed to cover the apartment bedroom

The number of rolls of groovy flowered wallpaper needed to cover the apartment wall is 9 rolls

Step-by-step explanation:

Here we have the area of the room wall to be covered is given by

2×L×H + 2 × W × H

Where:

Length, L  = 16 ft

Width, W = 10 ft and

Height, H = 8 ft

Which gives

2 × 16 × 8 + 2 × 10 × 8 = 416 ft²

Therefore, the number of rolls pf wall paper required = 8.32 rolls

Which means 9 rolls will be needed for the interior decoration as the rolls come in 50 ft² each.
