Question

A house plan shows a scale of 1:40. If the rectangular lounge room of the house is to measure 4.5 metres by 6.3 metres, What are the dimensions of the room on the plan?​

Answer 1

.112 m by .157m OR 4.43 by 6.20 in

Explanation:

The scale is 1:40, meaning that if the house plan shows 1 of something, the real life version is 40 times larger. Given this information:

4.5 m by 6.3 m is the ACTUAL SIZE.

Given this, we need to divide by 40 to get the room PLAN.

0.1125 by 0.1575 meters, OR 4.42913386 by 6.2007874 inches.

Simplifed,

.112 m by .157m OR 4.43 by 6.20 in
