Question

The figure below is a scale drawing of an office courtyard using the scale 1 centimeter = 4 feet.

Answer 1

Using proportions, it is found that option A gives a figure that is a scale drawing of the same courtyard using the scale 1 centimeter = 3 feet.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Researching this problem on the internet, the figure with a scale of 1 cm = 4 feet has the dimensions of:

51 cm, 75 cm, 30 cm and 72cm.

For a scale of 1 centimeter = 3 feet, these measures will be multiplied by 4/3, hence the figure is given in option A, as:

• 51 x 4/3 = 68 cm.

• 75 x 4/3 = 100 cm.

• 30 x 4/3 = 40 cm.

• 72 x 4/3 = 96 cm.
