How much will it cost to carpet a 13 ft by 18 ft room if carpeting costs $14.50 per square yard?
I know you either find the perimeter or the area. and when I figure both of them I get
P=2(13+18)
P=62
62*14.50= 899
or
A=13*18
A=234
234*14.50
3393
But I don't know which one it is can anyone help?
Neither is correct.
You need the area of a rectangle. First, get the measurement in yards.
13 ft. = 4.33 yd.
18 ft. = 6 yd.
A = L * W
A = 4.33 * 6
A = 25.98 = 26 yards
26 * 14.5 = $377.00
To calculate the cost of carpeting a room, we need to find the area of the room. In this case, you have correctly calculated the area as 234 square feet.
However, the given price of $14.50 is per square yard, not per square foot. So, we need to convert the area from square feet to square yards.
1 yard = 3 feet, so 1 square yard = 3 feet * 3 feet = 9 square feet.
To convert the area from square feet to square yards, divide the area (234 square feet) by 9:
234 square feet / 9 = 26 square yards.
Now, multiply the area in square yards (26) by the price per square yard ($14.50):
26 square yards * $14.50 = $377.
Therefore, it will cost $377 to carpet the 13 ft by 18 ft room at a price of $14.50 per square yard.
To determine the cost of carpeting a room, you need to calculate the area of the room, not the perimeter. The area of a rectangle (such as a room) is found by multiplying its length and width.
So, in this case:
Length of the room = 13 ft
Width of the room = 18 ft
To calculate the area:
Area = Length × Width
Area = 13 ft × 18 ft
Area = 234 square feet
Now, you mentioned that the carpeting costs $14.50 per square yard. In order to calculate the cost of carpeting the room, we need to convert the area from square feet to square yards. There are 9 square feet in a square yard (since 1 yard = 3 feet and 1 square yard = 3 ft × 3 ft = 9 sq ft).
So, to convert the area from square feet to square yards:
Area in square yards = Area in square feet ÷ 9
Area in square yards = 234 sq ft ÷ 9
Area in square yards ≈ 26 sq yd (rounded to the nearest whole number)
Finally, to calculate the cost of carpeting the room:
Cost of carpeting = Area in square yards × Price per square yard
Cost of carpeting = 26 sq yd × $14.50
Cost of carpeting ≈ $377
So, it would cost approximately $377 to carpet a 13 ft by 18 ft room if the carpeting costs $14.50 per square yard.
