A scale drawing of a kitchen is shown below. The scale is 1 : 20.

5 inches
4 inches
Show your work to determine the area of the room in square feet

5 inches = 100 inches

4 inches = 80 inches

Area = 100 inches x 80 inches
Area = 8000 square inches

1 square foot = 144 square inches

8000 square inches / 144 square inches = 55.55 square feet

Area of the room = 55.55 square feet

Statements like:

5 inches = 100 inches
4 inches = 80 inches

seem to make sense to the bot, but they surely are nonsense statements
for me
