You are making a dragonfly kite. You want to cover the non shaded area of the wings in shiny nylon. The demotions of one pair of wings are shown. Decompose the figure into simple shapes. How many square meters of nylon will you need to cover the non shaded area of one pair of wings
To decompose the figure into simple shapes, we can break it down into a rectangle and two right triangles.
The dimensions of the rectangle are 15 cm by 85 cm, giving us an area of 15 cm x 85 cm = 1275 square cm.
The dimensions of each right triangle are 15 cm (base) by 30 cm (height), giving us an area of 0.5 x 15 cm x 30 cm = 225 square cm for each triangle.
Therefore, the total area of the non-shaded part of one pair of wings is 2 x (1275 + 225) = 3000 square cm = 0.3 square meters.
So, you will need 0.3 square meters of shiny nylon to cover the non-shaded area of one pair of wings.
