Question

Wendy wants to put a wallpaper border around her bedroom. The room has two walls that each measure 10 feet 5

inches and two walls that each measure 6 feet 1 inch.
How many yards of wallpaper border must Wendy buy?
5.5 yards
11 yards
16 yards
33 yards

Answer 1

Wendy must calculate the total length of the walls in inches and then convert that measurement into yards. After adding the lengths of all four walls and converting the sum into yards, it is determined that Wendy needs to buy 11 yards of wallpaper border.

Step-by-step explanation:

To determine how many yards of wallpaper border Wendy must buy, we first need to calculate the total length of all four walls in her bedroom. There are two walls that measure 10 feet 5 inches and two walls that measure 6 feet 1 inch. To make the calculations easier, we will convert these measurements into inches and then convert the total measurement into yards, since 1 yard = 3 feet = 36 inches.

• 
  
• Each of the longer walls is 10 feet 5 inches: (10 ft × 12 in/ft) + 5 in = 125 inches per wall.
• 
  
• Each of the shorter walls is 6 feet 1 inch: (6 ft × 12 in/ft) + 1 in = 73 inches per wall.
• 
  
• Total inch measurement for all walls: (2 × 125 in) + (2 × 73 in) = 250 in + 146 in = 396 inches.
• 
  
• Convert inches to yards: 396 in / 36 in/yd = 11 yards.

Therefore, Wendy needs to buy 11 yards of wallpaper border to go around her bedroom.

Answer 2

11 yards

Step-by-step explanation:

The room has two sides both measuring 10 feet 5 inches. This gives a total of 20 feet 10 inches. It also has the other two sides both measuring 6 feet 1 inch and that too gives a total of 12 feet 2 inches. Adding them all together results in 32 feet 12 inches. Better still, the perimeter of the room is derived as;

Perimeter = 2 (L + W)

Perimeter = 2 (10'5" + 6'1")

Perimeter = 2(16'6")

Perimeter = 32'12"

Having in mind our conversion rate of 12 inches equals 1 foot, the results can be properly expressed as 32 feet plus 1 foot which gives us 33 feet.

If the perimeter of Wendy's room is now given as 33 feet, the conversion rate between feet and yards can now be applied. Having been given that

3 feet = 1 yard

Then 1 yard = 3 feet/3, that is

y = 3/3

Hence,

y = 33/3

y = 11

The results show that Wendy would needs to buy a total of 11 yards of wallpaper border.
