XV in Roman Numerals is 15.
XV is a class of brilliant people studying Digital Media at Hyper Island, Karlskrona, Sweden graduating in 2011.
Square Root of a MillionThe square root of a million is 1,000.
RangeThe term for the difference between the smallest and the largest values in a set of data is called the range. It is probably derived from the idea that the values of the numbers in the data could range anywhere from the lowest to the highest values but not beyond. The range is a measure of how disperse (spread out) the values are but it is not a very powerful measure.
"It's impossible to tell from the information you have given. An unlimited number of shapes could have the dimensions given. We would need to know one interior angle to calculate the area. It would probably be necessary to know two in a strict mathematical sense, but one would narrow it down to two possibilities, one of which would be unlikely because it would be sort of a crescent shape."
Although this is technically the right answer... . Using autocad I drew a trapezoid. The two parallel sides are 50' and 30'. On the left of the quadrilateral is the 64' side, and the side that is out of square comes out to roughly 67'-11-1/16". This to me indicates that your teacher attempted to indicate a trapezoid, with two right angles, and that the measurement of the final side was an approximation. This would keep you from being confused by feet, inches, and fractions of inches, which are a pain. If indeed two sides are parallel, the formula is H*((W1+W2)/2). What this means is that the side which is "square", but that is not parallel to any other line, is the height. In this case 64. W1 and W2 represent the two parallel sides and are 50 and 30. Therefore, what you are doing is taking an average width for the figure, and multiplying that by the height, in order to determine the area. 64*((50+30)/2)= 64*40 = 2560. In order to calculate the area of an irregular figure, you use a square to create right triangles. If no such dimensions exist, you must use a scale to approximate the size of each triangle in order to get the dimensions, and then use the formula (H*W)/2 to calculate each triangle's area. You then add the area of each triangle to get the total area. I assume your teacher's drawing was actually a trapezoid.
