Question

An architect makes a scale drawing of a building. She uses the scale shown. 1 centimeter =4 meters The length of the building in the drawing is 12 centimeters. What is the actual length, in meters, of the building?

Answer 1

To find the actual length of the building, multiply the drawing length (12 cm) by the scale factor (4 meters/cm), resulting in an actual length of 48 meters.

Step-by-step explanation:

An architect makes a scale drawing of a building, using a scale where 1 centimeter on the drawing corresponds to 4 meters of the actual building. In this case, the length of the building in the drawing is given as 12 centimeters. To find the actual length of the building, you use the scale factor provided:

• Multiply the drawing length by the scale factor: 12 cm × 4 meters/cm.
• That calculation gives you the actual length of the building: 12 × 4 = 48 meters.

Therefore, the actual length, in meters, of the building is 48 meters.
