Construction: One end of this storage shed will be left open, except for the gable. The area shaded in red is the gable. The area shaded in blue is the open end. Metal panels: Each side and end panel measures 6' high by 2' 6" wide. Each roof panel measures 4' 1" long by 2' 6" wide. Each of the two gable closures measures 1' 6" high by 7' 6" wide. For this storage shed one end will be left open, except for the gable. Reminder: The Pythagorean Theorem will be useful here. Refer to the graphic above to answer the question. What is the surface area of the sides and closed rectangular end?
