Short Answer 
To calculate the area of various shapes, first gather all necessary measurements for each shape. Then, apply the appropriate area formulas for each shape, such as the rectangle, triangle, and trapezoid, before calculating and summarizing the results for reference.
Step 1: Identify Measurements
Begin by carefully collecting all necessary measurements for each shape. These measurements are crucial for calculating the area accurately. The relevant dimensions for the objects are:
- h = 19.1 in
- a = 6.7 ft
- e = 2.3 m
- y = 9.8 cm
- o = 71.6 ft
Step 2: Apply Area Formulas
Once you have the measurements, apply the correct area formulas corresponding to each shape. Each shape has its own formula, so ensure you use the right one for accurate computation:
- Rectangle: Use the formula based on your values for h and a.
- Triangle: Integrate the measurements of s, y, and other dimensions into the triangle area formula.
- Trapezoid: Make sure to use the trapezoidal area formula as needed.
Step 3: Calculate and Summarize Areas
After applying the formulas, compute the area for each object and summarize the results. Document these areas clearly so that you can refer back to them easily. Your final areas will be tied to the following computations:
- Area of Rectangle
- Area of Triangle
- Area of Trapezoid
