Find the lengths of the unknown sides and hence calculate the perimeters of the figures below. Assume that all corners are right angles.---**Other Relevant Text:** 6 **Chart/Diagram Description:** Type: Geometric figure (a polygon) Main Elements: - A shape composed of straight line segments forming an L-shape with an additional step. - Side lengths are labeled: 5 cm (top horizontal), 4 cm (left vertical), 2 cm (bottom horizontal left part), 1 cm (right vertical part). - There is a dashed horizontal line segment inside the figure, labeled 6 cm. This line connects the inner corner to the rightmost vertical side. - Double tick marks are present on the top horizontal segment labeled 5 cm and the small horizontal segment on the upper right. This might indicate these lengths are equal, which contradicts the labels 5 cm and the visual length of the step. The figure structure suggests the top segment of the step is 5 cm - (2 cm + (horizontal distance from inner corner to right)) if it was a simple rectangle subtraction. However, the 5cm is the entire top length. Let's assume the double ticks are indicating the small horizontal step segment length is equal to the segment where the 5cm is labeled. This seems unlikely given the shape. Let's ignore the ticks as potentially erroneous or irrelevant without context, and focus on the labeled lengths. - Units: cm (centimeters)
