Answer 1

Answer:

1/300​

Step-by-step explanation:

Answer 2

Given :

• A plot measurement in length×width is 30m×20m.
• Length drawn to represent length of plot is 15 cm

To find : R.F. of scale for plot drawing is.

Solution :

The R.F. of scale for plot drawing is 1:200

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of R.F. of scale used for drawing)

R.F. or Representative Factor = (Length in drawing / Actual length)

Here,

Actual length = Length of the plot = 30m = 3000cm

(As, 1m = 100cm)

And,

Length in drawing = 15cm

So,

R.F. of scale = (15/3000) = 1 : 200

(This will be considered as the final result.)

Hence, the R.F. of scale for plot drawing is 1:200
