Question

The length of one side of the school building is 100 feet. if you use a scale factor of 1:250, what is the length of your scale drawing?
Please help me and explain how you get your answer!

Answer 1

its 25000

A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale).

The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.

Example: this drawing has a scale of "1:10", so anything drawn with the size of "1" would have a size of "10" in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.

Answer 2

Your scale factor has no units , so we can put in any units we want.

how about
1 foot : 250 ft
or
12 inches : 250 ft
12/250 inches : 1 ft
1200/250 inches : 100 ft
4.8 inches : 100 ft
1 inch : 100/4.8 ft
1 inch : 20.83 ft

or

12/250 = x/100
250x = 1200
x = 4.8

so 4.8 ft represents 100ft
1 inch would represent 100/4.8 or 20.83 ft
