Q. Reba's dining room is 5 meters5\,\text{meters} wide and 7 meters7\,\text{meters} long. Reba wants to install a new wood floor. It will cost $3.12\$3.12 per square meter. How much will Reba's new floor cost?\newline$___\$\_\_\_
  1. Calculate Area: Calculate the area of Reba's dining room.\newlineTo find the area, we multiply the width by the length.\newlineArea = Width ×\times Length\newlineArea = 55 meters ×\times 77 meters\newlineArea = 3535 square meters
  2. Find Total Cost: Calculate the cost of the new wood floor.\newlineTo find the total cost, we multiply the area by the cost per square meter.\newlineTotal Cost = Area ×\times Cost per square meter\newlineTotal Cost = 3535 square meters ×\times $3.12\$3.12 per square meter\newlineTotal Cost = $109.20\$109.20
