Rosa is putting carpet in her rectangular bedroom. She made a scale drawing using the scale of 1 inch = 3 feet. In the drawing, the length is 5.5 inches and the width is 3.25 inches. If carpet cost $2.58 per square foot, how much will it cost to carpet the bedroom?

$415.0575

Step-by-step explanation:

Given:

Scale measurement

1 inch = 3 feet.

In the drawing, the length is 5.5 inches and the width is 3.25 inches.

Length = 5.5 × 3

= 16.5 feet

Width = 3.25 × 3

= 9.75 feet

Area of the bedroom = length × width

= 16.5 feet × 9.75 feet

= 160.875 square feet

carpets cost $2.58 per square foot

Cost of carpeting the bedroom = Area of the bedroom × cost of carpet per square foot

= 160.875 × 2.58

= $415.0575

Cost of carpeting the bedroom = $415.0575

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
