7th grade Scale Factor.

61cm

Living room scale factor 1:1

Bedroom scale factor 3:1

Step-by-step explanation:

The answer is 61cm because...

Step one Since we have two rooms we want to find the area of the living room first since it is the biggest. so we multiply 7cm times 7cm to get 49cm^2Step two Now we have to find the area of the Bedroom. In order to do so we are going to do the same thing here as we did to the living room. So we multiply 2cm times 6cm to get 12cm^2.Step 3 this is the solving step. To do so you need to add 12cm by 49 cm to get 61cmStep 4 we need to find the scale factor now. for the living room the scale factor would be 1:1 because it is the same number multiplied by itself.Step 5 we need to find the scale factor of the bedroomThe scale factor of the bedroom is 3:1 because 6 is three times as much as 2Hope this helped :)
