3 answers

To determine the area of the room in square feet, we first need to convert the measurements from inches to feet since the scale is 1:20.

Length: 4 inches x (1 foot / 12 inches) = 0.3333 feet
Width: 5 inches x (1 foot / 12 inches) = 0.4167 feet

Next, we calculate the area of the rectangle:

Area = Length x Width
Area = 0.3333 feet x 0.4167 feet
Area = 0.138888 square feet

Therefore, the area of the room in square feet is approximately 0.139 square feet.
is all of the three's necessary?
No, the area can be rounded to a more reasonable and practical value. Therefore, the area of the room in square feet can be approximated to 0.14 square feet.
