For us to know the wingspan of the model that was brought by Carla, we need to multiply the total wingspan of the Wright brothers' flyer to the scale factor that was given. The equation will be [ 48 inches * 1/40 = 1.2 inches ]. The answer is 1.2 inches.

Answer: <u>96</u> sq ft.

Step-by-step explanation:

      First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.

             A = L * W

             A = (10 ft) * (3 ft)

             A = 30 ft²

             30 ft² * 3 = 90 ft²

      Next, we will find the area of the two triangles.

             A = \frac{b*h}{2}

             A = \frac{3*2}{2}=\frac{6}{2} =3

             3 ft + 3 ft = 6 ft²

      Lastly, we will add them together for the total surface area.

90 ft² + 6 ft² = 96 ft²
