Q. Select the information that is not needed to solve the problem. Then solve the problem.\newlineA wallpaper border is being pasted on the walls of a rectangular room that measures 1414 feet by 1712 17 \frac{1}{2} feet. The cost of the border is $6.50 \$ 6.50 per foot.\newlineHow many feet of border is needed for the room?\newlineWhich piece of information is not needed?\newlinea)The cost of the border.\newlineb)The width of the room.\newlinec)The length of the room.\newlineThe room requires □ \square feet of border.
  1. Identify Unnecessary Information: First, identify the unnecessary information for calculating the border needed. The cost per foot of the border does not affect the length needed to cover the room's perimeter.
  2. Calculate Perimeter: Calculate the perimeter of the room to find out how much border is needed. The formula for the perimeter of a rectangle is 2(length+width)2(\text{length} + \text{width}). Here, the length is 17.517.5 feet and the width is 1414 feet.
  3. Perform Calculation: Perform the calculation: 2(17.5+14)=2(31.5)=632(17.5 + 14) = 2(31.5) = 63 feet. This is the total amount of border needed.
