A construction company is building the house show below. They need to use a scale of 1 in: 8f. They measured the drawing to find that that the height of the building is 2.5 in. Explain to the construction workers how they would use this information for calculate the height of the final building.
They would have to multiply 2.5in and 8 ft because the ratio is 1in:8ft and the inches go up and you have to keep the ratio at the same value so you multiply 2.5 and 8
