If a window opening is 38 cm by 90 cm, does it meet the 0.35 m^2 minimum area?

• A. Yes
• B. No
• C. Only if the 38 cm side is considered across both windows
• D. Only if combined with another window

Answer: (B)

The main idea is to compare the opening’s area to the required minimum by converting the dimensions to meters and multiplying them.

Convert the sides to meters: 38 cm is 0.38 m and 90 cm is 0.90 m. Multiply to find the area: 0.38 × 0.90 = 0.342 square meters. This is slightly below the required 0.35 m^2, so the opening does not meet the minimum area.

Because the minimum is for each individual opening, this window on its own fails to satisfy the requirement. Even though you might wonder about combining openings, the rule typically applies to each opening separately, unless the standard explicitly allows summing areas from multiple openings.
