05.01) A scale drawing of a bathroom is shown below:

A rectangle is shown. The length of the rectangle is labeled 2 inches. The width of the rectangle is labeled 3.5 inches. The scale is 1 to 20.

What is the area of the actual bathroom in square feet? Round your answer to the nearest whole number.

7 ft2

19 ft2

12 ft2

140 ft2

The scale of 1 to 20, means for every 1 inch on the drawing the actual size would be 20 inches.

The length is labeled 2 inches, so the actual length would be 2 * 20 = 40 inches.

The width is labeled as 3.5 inches, the actual length would be 3.5 x 20 = 70 inches.

Now convert the inches to feet by dividing each length by 12:

40 inches / 12 = 3.33 feet.

70 inches / 12 = 5.83 feet.

Multiply them together for total area:

3.33 x 5.83 = 19.4 feet^2

Rounded to the nearest whole number = 19ft^2
