To decompose the figure into simple shapes, we can break it down into a triangle and a trapezoid.
The area of the triangle can be calculated using the formula:
Area = (base x height) / 2
Area = (3 x 3) / 2
Area = 4.5 square meters
The area of the trapezoid can be calculated using the formula:
Area = (a + b) x h / 2
Area = (3 + 4) x 3 / 2
Area = 10.5 square meters
Adding the areas of the triangle and trapezoid together:
4.5 + 10.5 = 15 square meters
Therefore, you will need 15 square meters of shiny nylon to cover the non-shaded area of one pair of wings.
The closest option provided is:
d. 2.38 square meters
However, this option is significantly lower than the actual area calculated, so the correct answer is not included in the given options.
