What is a scale drawing?
A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.
The area of the room can be calculated as;
The length of the room = 20 x 4 = 80 inches
The width of the room = 20 x 5 = 100 inches.
Now, 1 inch = 1/12 foot
80 inches / 12 = 6 2/3 ft
100 / 12 = 8 1/3 ft
The Area = 6 2/3 x 8 1/3
The Area = 25/3 x 20/3
The Area = 500 / 3
The Area = 166 2/3 ft²
Therefore, The area of the given room is 166 2/3 ft².
