Accepted Solution

A:
Answer:The correct answer is A. 60 square feet.Step-by-step explanation:1. Let's review the data provided to us for solving the question:The gazebo in Mr. Chang's backyard, according to the figure, is a square pyramid because its base is a square of 6 feet as length of its sides.Length of the sides of the base = 6 feetSlant length = 5 feetHeight = 4 feet2. How much cloth, in square feet, will Mr. Chang need, assuming he does not need to replace the cloth at the bottom of the figure?Area of a square pyramid = Base area + 1/2 Perimeter * Slant lengthReplacing with the real values, we have:Area of a square pyramid = 6 * 6 + 1/2 (6 + 6 + 6 + 6) * 5Area of a square pyramid = 36 + 1/2 (24) * 5Area of a square pyramid = 36 + 12 * 5Area of a square pyramid = 36 + 60Area of a square pyramid = 96 feet ²3. But remember than Mr. Chang doesn't need to replace the cloth at the bottom of the gazebo.So we need to subtract the area of the base to the area of the square pyramid:Area of the square pyramid - area of the baseArea of the base = 6 * 6 = 36 feet ²96 feet ² - 36 feet ² = 60 feet ²The correct answer is A. 60 square feet.
