Jawaban:
To find the cost of covering the entire loft with insulation, we need to calculate the area of the loft first.
The width of the loft is given as 700 centimeters and the length is given as 1100 centimeters.
Area of the loft = width x length
Converting the measurements to meters:
Width = 700 centimeters = 7 meters
Length = 1100 centimeters = 11 meters
Area of the loft = 7 meters x 11 meters = 77 square meters
Now, we can calculate the cost of covering the entire loft with insulation. Given that the cost is $3 per square meter:
Cost = Area x Cost per square meter
Cost = 77 square meters x $3 = $231
Therefore, it will cost $231 to cover the entire loft with insulation.
