The document you uploaded is a practical math assignment for estimating costs in construction and renovation, involving calculations for a house, including:

1. **Superficie à tourber** (area for turf) in m².
2. **Length of roof truss wood** in feet.
3. **Length of the staircase handrail** in inches.
4. **Angle of elevation of the staircase** in degrees.
5. **Cost of wallpaper** in dollars, based on specific areas.
6. **Total area to cover with plywood** in m².

Each task demands precise calculations, rounded to three decimal places, and well-structured methods. The context includes:
- The terrain is a trapezoid.
- Dimensions for walls, floors, and specific details about the structure, such as roof overhangs and staircase specifications.

Would you like assistance in solving any particular question, verifying calculations, or a step-by-step guide on one of the problems? Let me know which aspect you want to focus on.

### 5 Follow-Up Questions
1. Would you like a formula or explanation for calculating the area of a trapezoid?
2. Do you need help determining the total surface area of the roof and trusses for wood length estimation?
3. Should we calculate the number of steps and ramp length for the staircase?
4. Are you looking for guidance on how to find the cost of the wallpaper based on the given rates?
5. Do you need clarification or step-by-step instructions for calculating the plywood coverage?

### One Tip
For unit consistency, always convert all measurements to the same unit before starting calculations (e.g., feet to inches or meters). This prevents errors and simplifies the process.

The document focuses on practical mathematics for estimating construction and renovation costs, including tasks such as calculating turf area, roof truss length, staircase ramp, angle of elevation, wallpaper cost, and plywood coverage.

Explore practical mathematics for construction and renovation. Learn to estimate turf area, calculate roof truss lengths, determine staircase angles, and compute plywood and wallpaper costs with precision. Perfect for advanced students or professionals in construction-related fields.
