Question 197822
<font face="Garamond" size="+2">


You defined a rectangle, then asked for the perimeter of the triangle.  What triangle?


If you really meant the perimeter of the rectangle, then use the distance formula to find the length and width.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d = sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}]


where *[tex \Large (x_1,y_1)] and *[tex \Large (x_2,y_2)] are the coordinates of the endpoints of the segment for which you wish to determine the measure, and then use the formula for the perimeter of a rectangle:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ P = 2l + 2w]


To graph it, simply plot the four points and connect the dots.
