Does your project involve redecoration or renovation? New flooring? New carpets?

 

If you have wandered through a carpet outlet, you may have noticed that the price is often quoted by square metre and by square yard. Most often, the price per square yard is featured more prominently, since the price per yard is less than the price per metre. Regardless of whether you purchase your carpet by the square yard or by the square metre for a given area, you will pay the same amount.

 

One reason for working in the imperial system is that most carpet sold in North America is manufactured in 12-ft widths. How much would the carpet cost to cover a bedroom floor 9 ft × 12 ft if the carpet is advertised at $35.00 per square yard?

 

In this lesson you will explore the following questions:

  • How are areas commonly measured in the imperial system?
  • What is the history of area units in the imperial system?
  • How are imperial system area units related?
  • How are imperial system area units applied in practical situations?
  • How can you convert between imperial area units and area units in the SI (metric) system?
