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.

100 feet long
25 feet wide

To calculate the number of rolls of insulation needed, we need to find the total area of the attic and garage.

The area of the attic is 100 feet long and 25 feet wide, so its total area is 100 feet * 25 feet = 2500 square feet.

Since each roll of insulation is 1.25 feet wide and 50 feet long, its area is 1.25 feet * 50 feet = 62.5 square feet.

To find the number of rolls needed, we divide the total area of the attic and garage by the area of each roll:
Number of rolls = Total area / Area of each roll = 2500 square feet / 62.5 square feet = <<2500/62.5=40>>40 rolls.

Therefore, Mr. Garcia needs 40 rolls of insulation to cover his attic and garage.

To calculate the total area that Mr. Garcia needs to cover in the attic and garage, we first need to calculate the area of each space separately.

1. Attic:
The attic's dimensions are 100 feet long and 25 feet wide. To find the area, multiply these dimensions:
Area = Length x Width = 100 ft x 25 ft = 2500 square feet.

2. Garage:
Since you didn't provide the width of the garage, I will assume it to be the same as the attic, 25 feet.
The garage's dimensions are 100 feet long and 25 feet wide (assuming). To find the area, multiply these dimensions:
Area = Length x Width = 100 ft x 25 ft = 2500 square feet.

Now, to get the total area that Mr. Garcia needs to cover, sum the areas of the attic and garage:
Total area = Area of attic + Area of garage = 2500 square feet + 2500 square feet = 5000 square feet.

Therefore, Mr. Garcia needs to cover a total area of 5000 square feet in his attic and garage.

To find out how many rolls of insulation Mr. Garcia needs for the attic, we need to calculate the area of the attic first.

The area of a rectangle is calculated by multiplying its length by its width. In this case, the length of the attic is given as 100 feet and the width is given as 25 feet.

So, Attic Area = Length x Width = 100 feet x 25 feet = 2500 square feet

Now, to find out how many rolls of insulation are needed, we need to divide the total area of the attic by the area covered by a single roll of insulation.

The area covered by a roll of insulation is calculated by multiplying its width by its length. In this case, the width of a roll of insulation is given as 1.25 feet and the length is given as 50 feet.

So, Area covered by a roll of insulation = Width x Length = 1.25 feet x 50 feet = 62.5 square feet

Now, we can calculate the number of rolls of insulation needed for the attic:

Number of rolls = Attic Area / Area covered by a roll of insulation = 2500 square feet / 62.5 square feet = 40 rolls

Therefore, Mr. Garcia needs 40 rolls of insulation for his attic.

To calculate the number of rolls of insulation needed for the garage, you can follow the same process using the given dimensions of the garage.
