Quadrilateral Area Given Side LengthsDate: 8/24/96 at 0:34:55 From: Anonymous Subject: Area of Quadrilateral of Given Side Lengths I need to find the area of a 4 sided figure with dimensions of: a = Top side = 105 b = Right = 230.67 c = Bottom = 150 d = Left = 182.5 If I draw a diagonal "z" from the top-right (intersection of a&b) to the bottom-left (intersection of c&d) it becomes 2 triangles. Using the law of cosines leaves me with more unknowns than equations.

For example, suppose I told you to find the area of a four-sided figure with dimensions of 1 by 1 by 1 by 1. It could be a square with area 1 or it could be a parallelogram. The area would be very, very small if the parallelogram had two angles near 0. -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
