 Needing the area of an irregular Pentagon 2017-12-06 From Dale:I'm needing to find the square footage of an irregular pentagon. I've seen the other questions similar to this one, but without a great deal of difficulty can't get you the angle degrees, or the length between opposing angles. I'm hoping that a different bit of information can help. So here goes: The longest side is 67ft long. One of its legs is 39ft long, and the other is 18ft long. The leg off of the other end of the 39ft leg is 35ft long. The leg off of the other end of the 18ft is 49ft long, and meets the other end of the 35ft side. The information that I DO have, which I'm hoping makes the difference, is that the 39ft and the 18ft sides are parallel. Also, while the angles at each end of the 67ft side are not right angles, they are fairly close to it, approximately 80 degrees at the 39 ft side corner, and 100 degrees at the 18ft side corner.

A fish tank in the shape of an irregular pentagon 2008-03-29 From richie:i am building a fish tank. it is going to be an irregular pentagon. the sides are going to be 24" 24" 8" 8" 32"(approximately) there will 3 right angles A, B, E my question is how to figure out the degree of the angles that are not right angles (C,D)?Answered by Chris Fisher. The area of an irregular pentagon 2007-04-14 From Steven:I have been given a coursework in which i have to investigate various shapes to find the one that would give the largest area with 1000m perimeter. I'm stuck in a part where i have to calculate the area of a irregular pentagon. i don't know where to start from. I can make up the length of all the sides (5 sides), so long they add up to 1000, but i'm not quite sure what to do after that.Answered by Penny Nom. The area of an irregular pentagon 2007-03-26 From grace:hi I am doing graphics and need to find the area of the section given to us (it is just drawn). the sides measure 15m, 35.4m, 5m, 17.8m, 35.7m. the angle between the 15m side and the 35.4m side is 17degrees, the angle between the 35.4m side and the 5m side is 73degrees. the angle between the 5m side and the 17.8m side is 151degrees, the angle between the 17.8m side and the 35.7m side is 90degrees and the angle between the 35.7m side and the 15m side is 95degrees. if you could tell me the area i would be extremely grateful. thanks very much.Answered by Penny Nom. An irregular pentagon 2007-03-08 From kelly:If I have a pentagon with 2 sides of length 5 and one with a length of 2, what are the lengths of other 2 sides?Answered by Stephen La Rocque. An irregular polygon 2001-02-09 From Jason:I have a 5 sided irregular polygon I am trying to figure out the area of. There are no right angles in the polygon as far as I can tell. I do not know any angles.Answered by Chris Fisher.
