Estimate the material costs for wallcovering a room measuring 22ft (6.7 m) wide by 21 feet (6.4 m) long. -The ceiling height is 9 ft (2.7 m). -There are 2 windows and three doors. -The room is to be covered in a 54 inch (137 cm) wide vinyl wallcovering. -The wallcovering costs $13 per linear foot ($41.60 per linear meter). -The wallcovering is sold in full yards or full 30-yard (27 m) bolts, with a $3.00 cutting fee for orders under 30 yards. What is the total cost of the material needed to cover the room?
Step 1: Calculate the perimeter of the room 22 + 22 + 21 + 21 = 86 linear feet Step 2: Multiply the perimeter by the height to be covered. 86 × 9 = 774 linear feet Step 3: Since the roll is 54 inches wide, the doors and windows are not significant. Most doors and windows would be under 54 inches wide. Step 4: The 54″ wallcovering is sold by the linear yard, so you must calculate the linear yardage. To do this, divide Step 2 by 13.5 (13.5 square feet per yard in 54-inch goods). Step 5: The cost is given in feet, so you have to convert that to the price per yard. 3 ft=1 yard, so multiply the cost by $13 × 3= $39 per linear yard. Step 6: Calculate total cost by multiplying total linear yards by cost per yard.58 × 39 = $2,262 total cost
