Julio makes a scale drawing of the kitchen floor to determine how
tatuchka [14]

The scale drawing of Julio's kitchen would change the kitchen size

The actual area is 243 square feet

<h3>How to determine the actual area of Julio's kitchen?</h3>

The parameters are given as:

  • Length = 4.5 inches
  • Width = 3.375 inches

Start by converting the dimensions to feet using the scale ratio

  • Actual length = 4.5 inches/ (1 inch/ 4 feet) = 18 feet
  • Actual width = 3.375 inches/ (1 inch/ 4 feet) = 13.5 feet

The area is then calculated as:

Actual Area = Actual length * Actual Width

This gives

Actual Area =18 feet * 13.5 feet

Evaluate the product

Actual Area = 243 square feet

Hence, the actual area is 243 square feet
