Part (a): Calculate the surface area of the

• i. floors of the parlor and lobby.
  • Area of parlor floor = Length $\times$ Width = $4.00 \text{ m} \times 3.00 \text{ m} = 12.00 \text{ m}^2$
  • Area of lobby floor = Length $\times$ Width = $2.00 \text{ m} \times 1.50 \text{ m} = 3.00 \text{ m}^2$
  • Total surface area = $12.00 m^2 + 3.0
