Question

Find the missing dimension use the scale factor 1:12 model 32 cm find the actual in m

Answer 1

Given:

The scale factor is 1:12.

Dimension of model = 32 cm

To find:

The actual dimension in m.

Solution:

Let x be the actual dimension.

The scale factor is 1:12 and the dimension of model is 32 cm.

`(1)/(12)=(32)/(x)`

On cross multiplication, we get

`x=32* 12`

`x=384\ cm`

`x=3.84\ m`
`[\because 1\ m=100\ cm]`

Therefore, the actual dimension is 3.84 m.
