Karen is buying wallpaper border for her bedroom
Which is 12ft by 13ft. If the border is sold in rolls of 5yards each how many rolls will she need to purchase?
156ft. Divide by 3 is total 52 yrds. So divide by 5 yd 10 for 50 yard.karen would need at 11 rolls is that right?
No.
P = 2L + 2W
P = 24 + 26
P = 50 feet
50/3 = 16.67 yards
16.67 / 5 = 3.33 = 4 rolls
Well, Karen sure has big plans for her bedroom! Let's calculate this step by step. If her bedroom is 12ft by 13ft, the total perimeter would be 12 + 12 + 13 + 13 = 50 ft. However, since the border is sold in rolls of 5 yards, which is 15ft, we need to convert 50ft into yards. So, 50ft divided by 3 is about 16.67 yards. Then, if we divide 16.67 yards by 5 yards, we get around 3.33 rolls. So, Karen would actually need 4 rolls of wallpaper border to cover the perimeter of her bedroom. Time to get rolling!
To calculate the number of rolls Karen will need, we need to determine the total length of the wallpaper border required.
Given that her bedroom is 12ft by 13ft, we need to calculate the perimeter:
Perimeter = 2(Length + Width)
Perimeter = 2(12ft + 13ft)
Perimeter = 2(25ft)
Perimeter = 50ft
Now, since the border is sold in rolls of 5 yards, we need to convert the perimeter from feet to yards:
50ft ÷ 3ft/yd = 16.67 yards
To round up to the nearest whole number, we can consider the width of the rolls, so:
16.67 yards ÷ 5 yards/roll = 3.33 rolls
Since we can't purchase a fraction of a roll, we will need to round up to the nearest whole number.
Hence, Karen would need to purchase a minimum of 4 rolls of wallpaper border.
To determine how many rolls of wallpaper border Karen would need to purchase, we can follow these steps:
1. Calculate the total perimeter of the bedroom: Since the bedroom's dimensions are 12ft by 13ft, the perimeter is equal to twice the sum of the length and width. So, 2*(12ft + 13ft) = 50ft.
2. Convert the perimeter from feet to yards: Since the rolls of wallpaper border are sold in yards, we need to convert the perimeter from feet to yards. Since 1 yard is equal to 3 feet, we can divide the perimeter by 3. So, 50ft ÷ 3 = 16.67 yards.
3. Round up the result to the nearest whole number of yards: Since Karen can only purchase full rolls of 5 yards each, we need to round up the result from step 2 to the nearest whole number. So, rounding up 16.67 yards gives us 17 yards.
4. Divide the rounded result by 5: To determine the number of rolls needed, we divide the rounded result from step 3 by the length of each roll (5 yards). So, 17 yards ÷ 5 yards/roll = 3.4 rolls.
5. Round up the result to the nearest whole number of rolls: Since Karen cannot purchase a fraction of a roll, we need to round up the result from step 4 to the nearest whole number. So, rounding up 3.4 rolls gives us 4 rolls.
Therefore, based on the given dimensions and the rolls of wallpaper border available, Karen would need to purchase 4 rolls.
