To calculate the area that needs to be covered in the attic and the garage, we need to calculate the area of each space separately.
Area of the attic:
Length of the attic = 25 feet
Width of the attic = 28 feet
Area of the attic = Length × Width = 25 feet × 28 feet = 700 square feet
Area of the garage:
Length of the garage = 25 feet
Width of the garage = 28 feet
Area of the garage = Length × Width = 25 feet × 28 feet = 700 square feet
Now, we need to calculate the number of rolls of insulation required for each area.
Roll width = 1.25 feet
Roll length = 50 feet
Number of rolls for the attic = Area of the attic / (Roll width × Roll length)
Number of rolls for the attic = 700 square feet / (1.25 feet × 50 feet) = 700 / 62.5 = 11.2 rolls
Since we can't purchase a fraction of a roll, we need to round up the number of rolls required.
Number of rolls for the attic = 12 rolls
Number of rolls for the garage = Area of the garage / (Roll width × Roll length)
Number of rolls for the garage = 700 square feet / (1.25 feet × 50 feet) = 700 / 62.5 = 11.2 rolls
Again, we need to round up the number of rolls required.
Number of rolls for the garage = 12 rolls
Therefore, Mr. Garcia needs 12 rolls of insulation for both the attic and the garage.
Mr. Garcia is replacing the insulation in his attic and garage. Each roll of insulation is 1.25 feet wide and 50 feet long. The picture shows the dimensions of the attic and the garage that he needs to cover.
25 feet long
