Question

A construction company is building the house shown below. They need to use a scale

Answer 1

The height of the building is calculated by representing 1 inch as 8 feet. The final building has a height of 20 feet.

What is scaling?

Scaling is the increase or decrease in the height of an object by a scale factor k.

Given that the scale used is:

1 inch = 8 feet. Hence:

Since the height of the building is 2.5 in, hence:

Height of the final building = 2.5 in * 8 ft per 1 in = 20 feet

The height of the final building is 20 feet.

Answer 2

Using proportions, we have that:

1. The height of the building is found using a rule of three.
2. The height is of 20 feet.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The scale is of 1 inch = 8 feet. What is the height for 2.5 inches? The rule of three is given by:

1 inch - 8 feet.

2.5 inches - x feet

Applying cross multiplication, the height in feet of the final building is given by:

x = 8 x 2.5 = 20 feet.
