I am trying to use excel to draw and calculate the
perimeter of a rectangle when given an algebraic
equation. Any help would be greatly appreciated
Any rectangle defined by an equation (or equations) is perforce defined with
respect to a coordinate system. That being so, it should be elementary to
determine the coordinates of the 4 corners of the rectangle. With those, the
perimeter of the rectangle is the sum of the lengths of the line segments
connecting the corner points, and those lengths are easily calculated.
Given one corner at (a,b) and an adjacent one at (c,d), the length of the line
segment joining them is
=SQRT(SUMSQ({c,d}-{a,b}))
