Question

A scale drawing of a building needs to be made using the scale 1 in = 250 ft. How tall will the building in the scale drawing be if the building is 750 ft tall?

The height of the building in the scale drawing will be ___ in.

Answer 1

The height of the building in the scale drawing will be 3 in.

Explanation:

This question is solved by proportions, using a rule of three.

In the drawing, each inch represents 250 feet. So how many inches will be needed to represent 750 feet?

1 inch - 250 feet

x inches - 750 feet

Applying cross multiplication:

`250x = 750`

`x = (750)/(250)`

`x = 3`

So

The height of the building in the scale drawing will be 3 in.
