Ruth's dining room is 6 yards wide and 9 yards long. Ruth wants to install a new wood floor. It will cost $8.00 per square yard.

lara [203]

Ruth’s new floor cost $432.

The cost can be calculated as follows.

First, calculate the area of dining room. Use the formula of rectangle area (width x length)

Area = width x length

= 6 yd x 9 yd

= 54 sq yd

Second, calculate the total cost.

Cost = 54 sq yd x $ 8 per sq yd

= $ 432

Hence it cost $ 432 to install the new wood floor.
