3/2in ??
Do you mean 1 1/2 inches = 1 foot?

yes ido

One way to solve this problem is with proportions.
1.5/1 = 18/x
Cross multiply:
1.5x = 18
x = 18/1.5
x = 12 feet
Try the second dimension. I'll be glad to check your answer.

Your number is correct, but the unit is wrong. Your question asks what are the dimensions of her room.
I told you one of the dimensions is 12 feet. I don't think the other dimension is 16 inches.

Your welcome.
I hope you realize that the room measures 12 feet by 16 feet.
