1. Let's clarify the problem: We have a rectangle with one side marked by 1 tick (shorter side) and the other by 2 ticks (longer side). 2. Assuming the shorter side length is $x$ units (represented by 1 tick), then the longer side length is $2x$ units (represented by 2 ticks). 3. To find the perimeter of this rectangle, we use the formula: $$\text{Perimeter} = 2 \times (\text{shorter side} + \text{longer side})$$ 4. Substitute the side lengths: $$\text{Perimeter} = 2 \times (x + 2x) = 2 \times 3x = 6x$$ 5. Thus, the perimeter of the rectangle is $6x$ units, where $x$ is the length represented by one tick. If you want to find the area, it would be: $$\text{Area} = \text{shorter side} \times \text{longer side} = x \times 2x = 2x^2$$ Let me know if you want to solve for a specific length or a value for $x$.
