1. The problem asks to find the area of a shape with given dimensions 5, 4, and 1 square units. 2. Since the problem does not specify the shape, we assume it is a rectangle or a composite figure where these numbers represent lengths. 3. If these are sides of a rectangle, the area is calculated by the formula: $$\text{Area} = \text{length} \times \text{width}$$ 4. Using the given numbers, if 5 and 4 are the length and width, then: $$\text{Area} = 5 \times 4 = 20$$ 5. The number 1 might represent a unit or a separate dimension, but since the problem states "square units," the area is already in square units. 6. Therefore, the area is 20 square units.
