Woman using the Urinella, a type of female urination device, to adapt to standard men's room urinals. A female urination device, female urination aid, or stand-to-pee device (STP) is a device which aids a female to urinate while standing upright. Variations include basic disposable funnels to more elaborate reusable designs. Female urination devices have increased in popularity since the 1990s.
Each of the rectangles in the histogram has a base of 25, and the heights are 3, 7, 8, 10, 1, and 1. Thus the total area of the histogram is 3x25+7x25+8x25+10x25+1x25+1x25=750. We want the value with area 750/2=375 to the right of it and 375 to the left of it.
The dimensions of the rectangle are found by calculating the distance between various corner points. Recall that we can find the distance between any two points if we know their coordinates. (See Distance between Two Points) So in the figure above: 1  The height of the rectangle is the distance between A and B (or C,D).2  The width is the distance between B and C (or A,D). 3  The length of a diagonals is the distance between opposite corners, say B and D (or A,C since the diagonals are congruent).ut if the sides of the rectangle are parallel to the x and y axes, then the calculations can be a little easier. In the above figure uncheck the rotated box to create this condition and note that: 1  The height is the difference in y-coordinates of any top and bottom point-for example A and B.
