4) Sara asks Ryan to figure out the total area of the sail for the 12 foot sailboat she is making. She draws a scaled picture of the sail she wants to make from a photograph and writes in the lengths from the picture, see drawing. Ryan sees it is an isosceles triangle. If she wants the bottom of the sail for her boat to be 13.5 feet long, what will the area be?
