Chapter 1, Problem 99b
A house has an area of 195 m2. What is its area in each unit? a. km2 b. dm2 c. cm2
Verified step by step guidance1
Identify the conversion factors for each unit: 1 km^2 = 1,000,000 m^2, 1 m^2 = 100 dm^2, and 1 m^2 = 10,000 cm^2.
Convert the area from m^2 to km^2 by dividing the given area by 1,000,000.
Convert the area from m^2 to dm^2 by multiplying the given area by 100.
Convert the area from m^2 to cm^2 by multiplying the given area by 10,000.
Ensure each conversion is done correctly by checking the units and conversion factors used.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Unit Conversion
Unit conversion is the process of converting a quantity expressed in one unit to another unit. In this case, it involves converting the area of a house from square meters (m²) to other area units such as square kilometers (km²), square decimeters (dm²), and square centimeters (cm²). Understanding the relationships between these units is essential for accurate conversion.

Conversion Factors
Area Measurement
Area measurement quantifies the extent of a two-dimensional surface. It is typically expressed in square units, such as square meters, which represent the area of a square with sides of one meter. Knowing how to calculate and express area in different units is crucial for applications in real estate, architecture, and land use.

Metric System
The metric system is a decimal-based system of measurement used globally, which includes units such as meters, liters, and grams. It is structured in powers of ten, making conversions between units straightforward. Familiarity with the metric system is important for performing calculations and conversions in scientific contexts, including area measurements.
