The answer is C, 135. To find the solution, first find the area of the closet by multiplying 3 by 5, which is 15. Then, find the area of the entire room by multiplying 15 by 10 to get 150. Finally, subtract 15 from 150 to find the solution of 135 square feet.
If you're saying that the scale is 10 cm: 1 mm then the scale will be larger than the actual object because for every 1 mm of the object it will equal 10 cm of the scale drawing.
