A rectangle family room is 8 yards long and 5 yards wide . At $30 per square yard , how much will it cost to put down vinyl sheet flooring in the room ?

A = LW

8 * 5 = 40 square yards

40 * 30 = $____________

$120

To find the cost of putting down vinyl sheet flooring in the rectangle family room, you first need to calculate the area of the room.

The area of a rectangle can be found by multiplying its length by its width. In this case, the length of the room is 8 yards and the width is 5 yards. Therefore, the area of the room can be calculated as:

Area = length * width
Area = 8 yards * 5 yards
Area = 40 square yards

Now that we know the area of the room is 40 square yards, we can calculate the cost of the vinyl sheet flooring.

The cost per square yard is given as $30. Therefore, to find the total cost, we need to multiply the area of the room by the cost per square yard:

Total Cost = Area * Cost per square yard
Total Cost = 40 square yards * $30 per square yard
Total Cost = $1200

So, it will cost $1200 to put down vinyl sheet flooring in the rectangle family room.
