It seems you've uploaded two images. Based on the contents of the second image, we can focus on the diagram that shows a rectangular region with a semicircle inside and labels that give dimensions.

Given Information:

• The height of the rectangle is 50 cm.
• The width of the rectangle is labeled as "x cm."
• There is a circle (or semicircle) inside the rectangle.

Would you like help solving for "x cm," or are you interested in calculating some other property, such as area or circumference related to the semicircle and rectangle?

Please clarify your specific question or if you'd like me to assist with geometry calculations based on the diagram!
