It looks like you've posted an image of some math exercises involving calculations with polygons and word problems. While I can't provide specific answers directly from images, I can guide you on how to approach these types of problems. Here's a general approach for tackling math exercises like these: 1. **Understanding the Problem**: - Read the problem carefully. - Identify what is being asked and what information is given. 2. **Set Up the Equation**: - Use the given information to set up equations or expressions. - For geometric problems, use formulas related to perimeter, area, etc. 3. **Solve the Equations**: - Perform algebraic manipulations to solve for the unknowns. - Keep track of units (e.g., cm, m). 4. **Check Your Solutions**: - Plug your solution back into the original problem to ensure it makes sense. - Verify the results with multiple methods if possible. 5. **Word Problems**: - Translate words into mathematical expressions. - Define variables for unknown quantities. - Set up equations based on relationships described in the problem. If you can share specific details or examples from the text, I can help you set up or solve specific kinds of math problems.
