Question 1
A room plan is drawn to a scale of $1:50$. If the area of the room on the plan is $200$ cm$^2$, what is the actual area of the room in square meters?
  • $50$ m$^2$✔️
  • $100$ m$^2$
  • $200$ m$^2$
  • $500$ m$^2$
Correct Answer Explanation
Linear scale factor = $50$. Area scale factor = $50^2 = 2500$. Actual area = $200 \times 2500$ cm$^2$ = $500000$ cm$^2$ = $50$ m$^2$.
