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!

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.

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

To find the length of the scale drawing, we need to multiply the scale factor by the actual length.

The scale factor is given as 1:250. This means that 1 unit on the scale drawing represents 250 units in real life.

Given that the length of one side of the school building is 100 feet, we can set up a proportion to find the length of the scale drawing.

Let's represent the length of the scale drawing as 'x'.

100 feet (actual length) / x (scale drawing length) = 1 (scale factor) / 250

To solve for 'x', we can cross-multiply and solve for 'x':

100 * 250 = x * 1
25000 = x

Therefore, the length of the scale drawing is 25000 units.

I hope this helps!
