From the diagram, we observe the following details:

• The figure appears to be a quadrilateral labeled as $ABCD$ with the following measurements:
  • $AB = 12.5 \, \text{cm}$
  • $BC = 16 \, \text{cm}$
  • $CD = 24.3 \, \text{cm}$
  • $DA$: No measurement is provided, but it forms a diagonal with $AC$.
  • The diagonal $AC$ is labeled, forming angles with other sides.

The aim is likely to calculate:

1. The missing length of $DA$.
2. The area of the quadrilateral, which can be split into two triangles via diagonal $AC$.
3. Any required angles or properties.

Could you confirm your specific query regarding this diagram? For example:

• Are you looking for the area of the quadrilateral?
• Are you solving for side $DA$?
• Do you need any angles calculated?

Please clarify, and I can proceed with the solution!
