What is the scale of a drawing where a 6 meters wall is 4 centimeters long?

To determine the scale of the drawing, we need to calculate the ratio of the length of the wall in the drawing to its actual length.

Given:
Length of wall in drawing = 4 cm
Actual length of wall = 6 meters = 600 cm

Scale = Length in drawing / Actual length
Scale = 4 cm / 600 cm

Scale = 1:150

Therefore, the scale of the drawing is 1:150.
