Understanding the Problem

In this problem, we are given the dimensions of a room in feet and asked to find its approximate area in square meters. To solve this problem, we need to convert the dimensions from feet to meters and then calculate the area.

Why Convert Units?

Converting units is an essential skill in mathematics, particularly when working with different measurement systems. In this case, we are given the dimensions in feet, but we need to find the area in square meters. This requires us to convert the dimensions from feet to meters.

Converting Feet to Meters

To convert feet to meters, we need to know the conversion factor. There are 3.28084 feet in 1 meter. We can use this conversion factor to convert the dimensions from feet to meters.

Converting Length (10 ft) to Meters

To convert the length of 10 ft to meters, we can multiply it by the conversion factor:

10 ft × (1 m / 3.28084 ft) ≈ 3.048 m

Converting Width (20 ft) to Meters

To convert the width of 20 ft to meters, we can multiply it by the conversion factor:

20 ft × (1 m / 3.28084 ft) ≈ 6.096 m

Calculating Area in Square Meters

Now that we have the dimensions in meters, we can calculate the area of the room in square meters. The formula for the area of a rectangle is:

Area = Length × Width

Substituting the values we found earlier, we get:

Area = 3.048 m × 6.096 m ≈ 18.55 m^2

Comparing Answer Choices

Now that we have calculated the approximate area of the room in square meters, we can compare it with the answer choices:

A. 19 m^2 B. 200 m^2 C. 2,152 m^2 D. 9 m^2

Our calculated area of approximately 18.55 m^2 is closest to answer choice A, which is 19 m^2.

Conclusion

In this problem, we were given the dimensions of a room in feet and asked to find its approximate area in square meters. We converted the dimensions from feet to meters using the conversion factor and then calculated the area using the formula for the area of a rectangle. Our calculated area was closest to answer choice A, which is 19 m^2.
