Final answer:
The area of a rectangle home measuring 30.0 m by 20.0 m is calculated by multiplying the length by the width, resulting in an area of 600.0 square meters.
Step-by-step explanation:
The area of a rectangle is found by multiplying its length by its width. In the case of a home measuring 30.0 m in length and 20.0 m in width, we simply multiply these two dimensions to calculate the area.
Area = Length × Width
Area = 30.0 m × 20.0 m
Area = 600.0 m²
Therefore, the area occupied by the rectangle home is 600.0 square meters.
