Answer:
No, they cannot both be right
Step-by-step explanation:
Firstly, we need to convert the ft in the real room to inches
Mathematically; 1 foot = 12 inches
So 15 ft will be 15 * 12 = 180 inches
18 ft will be 18 * 12 = 216 inches
Now let’s look at their drawings;
9 to 10.8
So 9 translated to 180 while 10.8 translated to 216
So the ratios here are;
9/180 and 10.8/216 = 1 : 20 for the ratio of the drawing to the real measure
This shows that only Ricky is right
