Answer 1

To solve this problem you must apply the proccedure shown below:

1- Express six meters in centimeters:

`6m=600cm`

2- You know that the shorter side shown in the picture of the rectangular room is 5 centimeters, which represents 600 centimeters, therefore the scale of the picture is:

`600:5`

3. Divide by 5 to simplify it:

`120:1`

3. To calculate the larger side (
`L`)of the room , you need to keep on mind the scale obtained and multiply it by the larger side in the picture of the rectangular room:

`L=(7cm)(120)=840cm`

Therefore, the answer is: The scale of the picture is 120:1 and the longer side of the room is 840 centimeters.
