stage model ratios help!?

Question

Okay, im making a stage design model for school.
The actual stage is 12m by 18m (40 x 60 ft)
I need to make my model in porportion with the measurements...
The material i have for the base is 134cm by 83cm.
The material is easy to cut so i can cut it smaller if needed.
Can you help me with this, i hate measurement/ratios!

::Okay so i've been told the ratio i should use is 2:3 and that it should be 83cm by 124.5cm
Um little question about that? What does one metre equal to?

Answer 1

Its simple Elizabeth. For every 3 cm of length, make sure the width is 2 cm long. In other words, you could choose any ratio indeed.

To ease your problem, let's see what you need to do.

You have a base that is 134cm x 83cm. If you were to keep the 83cm edge as it is, you need the other edge to be one and a half times as long - i.e. 124.5cm.

If on the contrary you were to wish to have the 134cm long edge as it is, the other edge must be two-thirds of 134cm long - i.e. 89.33cm.

Now obviously you don't have a base with 134cm x 89.33cm. So the only choice is to cut the base such that, you have the 83cm edge intact and the 134cm edge reduces in length to 124.5cm.

So the resultant base should be:

124.5cm x 83cm

Answer 2

The ratio model is by simplifying the measurement of the actual stage:
12:18 divide both by 2
6:9 divide both by 3
2:3 after this it can't be simplified anymore

40:60 divide both by 10
4:6 divide both by 2
2:3

The ratio is 2:3 or 2/5 by 3/5. That is, there are 5 parts of which 2 goes to one side and 3 to the other.

As regards your material, 134 cm by 83 cm the ratio 134:83 can't be simplified anymore. If you want to lessen then ratio say by 5 times their original measurement then the new ratio with the same aspect will be:
134/5:83/5 or 26.8:16.6 or 26 4/5:16 3/5.

If you want it larger thrice you can maintain the same aspect by:
134 * 3:83 * 3 or 402:249.

Answer 3

it has to be a 2:3 ratio so if you cut the material the biggest size would be 83cm by 124.5cm, but any 2:3 ratio would work. ie 20 by 30, 50 by 75 ect.

Answer 4

If you cut the base to 80 cm by 120 cm, each measurement in the model will be 2 times each measurement in the actual world, but in cm instead of ft.
