Final answer:
The correct expression to find the combined total area of a village is Area = Length x Width, as this calculates the space inside the perimeter of a typically rectangular area.
Step-by-step explanation:
To find the combined total area of a village, which is typically represented as a rectangle, we use the formula for the area of a rectangle, A = length × width. This is the mathematical way of determining the space inside the perimeter of a rectangle and is used widely in geometry problems involving two-dimensional shapes.
When finding area, we do not use the formulas that pertain to calculating perimeters or adding lengths, but instead, use multiplication to find the number of square units that can fit within the shape. For instance, if the length of a rectangle is 6 meters and the width is 3 meters, the combined total area would be 6 × 3 = 18 square meters. Using the correct units of measurement is essential and multiplying the length by the width will give us a result in square units, such as square meters (m²).
Having a firm understanding of the concept of area can be very helpful in real-life situations, such as when a farmer is calculating the amount of fencing needed for a plot of land, or when comparing the sizes of two different plots or buildings.
