A scale drawing of the floor of a theater has a scale factor of 18. Mark says that he can use this information and any length on the scale drawing to find the corresponding length in the actual theater. He says that he can also use this information and any length in the actual theater to find the corresponding length on the scale drawing? Is he correct? I don't understand the problem. Please help me.

Question

Thank you!

Answer 1

of course he is right.

The actual room is 18 times as big as the drawing.

So, any length on the drawing, times 18, is the length in the room.

Any length in the room, divided by 18, is the length in the drawing.

That's the whole purpose of scale drawings - to represent the actual large object in a manageable size.

Maybe you should just ask Mark yourself. Go up to him and say, "Mark, are you right? Come on, make up your mind!!!!"
