the areas together.
However, there is a more efficient method to estimate the total floor area where you
only need to measure 4 lengths. Mark on the plan above the
four lengths that are
needed to estimate the total floor area of the apartment.
Translation Note: In some languages the term used for “area” varies according to the context. As this unit focuses on the areas of rooms, you may choose to use in the first instance here both terms with one between parentheses as in the FRE source version: “La superficie (l’aire) totale de l’appartement”.
