Answer :

Hello! I'll guide you through the calculations step by step to answer the questions provided. 1. To estimate the land area needed to provide Arizona's annual energy consumption: - Arizona's annual energy consumption is about 240,000 GWh. - Convert 240,000 GWh to kWh (1 GWh = 1,000,000 kWh) to get 240,000,000,000 kWh. - With solar panels generating about 200 Watt/m², convert this to kWh/m² (1 Watt = 0.001 kWh) to get 0.2 kWh/m². - Divide the total energy consumption by the energy generated per square meter to get the land area needed in square meters. - Convert the land area from square meters to square kilometers. 2. To estimate the length of a side of the square solar land: - Once you have the land area in square kilometers, find the square root to get the length of one side of the square. 3. To estimate the distance run in a marathon: - A marathon is typically 42.195 kilometers long. By following these steps, you can estimate the land area needed for solar panels in Arizona, the length of a side of the square solar land, and the distance of a marathon.
