Question

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?

Answer 1

Given:

The scale model of an object has a scale of 1cm : 2ft.

The actual object is 11 feet tall.

To find:

The height of the model.

Solution:

It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.

Let the height of the model be x cm.

`(x\ cm)/(11\ ft)=(1\ cm)/(2 \ ft)`

`x\ cm=(1 \ cm* 11\ ft)/(2 \ ft)`

`x\ cm=5.5\ cm`

Therefore, the model is 5.5 cm tall.
