Solution

To find the length of the building in the drawing, we need to use the scale provided.

Step 1: Understand the scale. The scale is 1 millimeter : 3 meters. This means that 1 millimeter on the drawing represents 3 meters in real life.

Step 2: Set up a proportion. We can set up a proportion to find the length of the building on the drawing. The proportion is 1 mm / 3 m = x mm / 150 m.

Step 3: Solve for x. Cross-multiply to solve for x.

1 mm * 150 m = 3 m * x mm

150 mm = 3x

x = 150 / 3

x = 50 mm

So, the building is 50 millimeters long in the drawing.
