Question

Number 3 plz I don't get when they say dimensions

Answer 1

Well 1 cm = 2ft, so it might be asking the scale?

Answer 2

Pretty much is asking what are the dimensions of the house, every 6 cm= 12 feet so u can easily add the cm of the house then divided and cheeck with multiplication. 
Like this: 10+7+9+9+8=43
43÷12=3r5 
The answer is 3r5, so the dimensions are 3 and 5
Im hoping i did it right cause i did this problem but id remember it
