Find the cost of carpeting the following rectangular
rooms:
a. Dimensions: 6.5 m * 4.5 m; cost = $13.85>m2
b. Dimensions: 15 ft * 11 ft; cost = $30>yd2
In each case, multiply the three numbers for the total cost for carpeting the room.
Can you explain a little more.
(length)x(width)x(cost per area)= (cost)
405.11
To find the cost of carpeting a rectangular room, you need to calculate the area of the room and then multiply it by the cost per unit of area.
a. Dimensions: 6.5 m * 4.5 m; cost = $13.85/m2
To find the area of the room, multiply the length and width:
Area = 6.5 m * 4.5 m = 29.25 m2
The cost can be found by multiplying the area by the cost per unit of area:
Cost = Area * Cost per m2 = 29.25 m2 * $13.85/m2 = $405.14
b. Dimensions: 15 ft * 11 ft; cost = $30/yd2
First, convert the dimensions from feet to yards:
Length = 15 ft * (1 yd/3 ft) = 5 yd
Width = 11 ft * (1 yd/3 ft) = 3.67 yd
To find the area of the room, multiply the length and width:
Area = 5 yd * 3.67 yd = 18.35 yd2
The cost can be found by multiplying the area by the cost per unit of area:
Cost = Area * Cost per yd2 = 18.35 yd2 * $30/yd2 = $550.50
So, the cost of carpeting the rectangular rooms are:
a. $405.14
b. $550.50
