if 4 feet is 1/4 inch. Divide the real measurements by 4 then by 4 again to get the model size.
20feet long /4=5 5/4=1.25
1.25 inches long
12feet wide /4=3 3/4=0.75
0.75 inches wide.

One Unit is 4 feet long. So there is Length = 20/4 = 5 and Width = 12/4 = 3 units
Each Unit on paper is 1/4 inch
Length is 5 x 1/4 = 5/4 = 1 1/4 inch
Width is 3 x 1/4 = 3/4 inch

12 inches in a foot, and every 4 feet is equal to 1/4 inch. The 20 feet room / 4 feet model scale = 5 feet. 5 feet X 12 inches = 60 inches. 60 X 1/4 = 15 inches is length of model.

the scale is 4' = 1/4"
so 20' (which is 5 times 4') will be 5 times 1/4" in the model
= 1 and 1/4 inches.
12 feet (which is 3 times 4 feet) will result in 3 times 1/4" in themodel which is 3/4"

the model of the room is 5/4 inches long and 3/4 inches wide
20=4x5 that means that the model should be 5 times a quarter of an inch because tthe actual room is 5 times 4 feet long.
5x1/4=5/4
same thing for width except different numbers
12=4x3 that means that the model should be 3 times a quarter of an inch because tthe actual room is 3 times 4 feet long.
3x1/4=3/4

You can divide the 20 feet by the 4 foot scale to determine how many scaled units you need. In this case, it's 5 units and your units are 0.25 inch long, so 5 units times 0.25 inches each = 1.25 inches.
