There is a triangular open space in the campus. Now we are going to plant turf on this open space to beautify the environment. We have measured its three side lengths of 13 meters, 14 meters and 15 meters respectively. If the price of this kind of turf is 120 yuan per square meter, how much will it cost to buy this kind of turf at least? So what? It's better to be complete

Make the height of the side 14
According to Pythagorean theorem, the length of this height is 12
So the area of this triangle is 1 / 2 * 14 * 12 = 84
The required expenditure is 120 * 84 = 10080 yuan

12. A meteorological research center observed the whole process of a sandstorm from its occurrence to its end. At the beginning, the wind speed increased by 2km / h on average. After 4h, the wind speed increased by 4km / h on average when the sandstorm passed through the open desert. For a period of time, the wind speed remained unchanged at 32km / h. When the sandstorm met the green vegetation area, the wind speed decreased by 1km / h on average. At 40H, the measured wind speed was 17km / h According to the images of wind speed and time, the following questions are answered: (1) fill in the corresponding values in the y-axis (); (2) how many hours have the sandstorm passed from the occurrence to the end?
