<div id="id_solution_display" class="markdown-body editormd-html-preview"><textarea>Area of the carpet of the dimension $$12$$ feet by $$10$$ feet $$=12 \times 10=120$$ square feet

The measurement of a room can be $$12$$ feet by $$10$$ feet.

$$60$$ inches by $$36$$ inches, $$100$$ centimeters by $$80$$ centimeters are too small for being the dimension of a room and $$20$$ meters by $$18$$ meters is too big for a room.

Therefore, the most reasonable dimension for Shelly's carpet be $$12$$ feet by $$10$$ feet.
