1. What is the area of the Wright Brother's rectangular planform?
2. Step 1: base = 6 ft.; height = 40 ft.

   Step 2: area of rectangle = b x h = 240 ft.²

    

3. What is the area of the F-18 (Blue Angels) trapezoidal planform?

   Step 1: height = 15 ft.; base 1 = 13 ft.; base 2 = 6 ft.

   Step 2: area of trapezoid = ( h / 2 )( b₁ + b₂ ) = 142.5 ft.²

4. What is the area of the Concorde triangular planform? (Note: These are not the actual dimensions.)
5. Step 1: base = 50 ft.; height = 25 ft.

   Step 2: area of triangle = ( 1 / 2 ) x b x h = 625 ft.²

    

6. What is the area of the Space Shuttle's compound planform? (Note: These are not the actual dimensions.)

   Step 1: Divide the shape into three regions. From left to right, they are a triangle, trapezoid, and rectangle.

   Step 2: Region 1: base = 13 ft.; height = 7.5 ft. (Calculate the area of this triangle.)

   1. Region 2: height = 18 ft.; base₁ = 31 ft.; base₂ = 7.5 ft. (Calculate the area of this trapezoid.)

      Region 3: base = 9 ft; height = 31 ft (Calculate the area of this rectangle.)

   Step 3: Add the areas of the three regions. Total area = 674.3 ft.²

    

7. What is the area of the Boeing 747 trapezoidal planform? (Note: These are not the actual dimensions. The trapezoidal planform cannot be divided into two right triangles. Hint: Divide the figure into two scalene triangles and compute their areas.)

   Step 1: Divide the shape into three regions. From left to right, they are a triangle, rectangle, and triangle.

   The height of the first triangle is a straight line drawn down from the upper left-hand corner of the shape.

   The height of the second triangle is a straight line drawn up from the bottom right-hand corner of the shape.

   Step 2: Region 1: base = 50 ft. , height = 77 ft. (Calculate the area of this triangle.)

   Region 2: base = 6 ft. , height = 77 ft. (Calculate the area of this rectangle.)

   Region 3: base = 19 ft , height = 77 ft (Calculate the area of this triangle.)

   Step 3: Add the areas of the three regions. Total area = 3118.5 ft.²
