Formulas for the Area of a FigureDate: 3/23/96 at 0:24:42 From: Anonymous Subject: Puzzled I am in 8th grade and I have 1 week left in Geometry and I still can't get how to find the area of a figure?! Can you PLEASE help? I am truly puzzled! Date: 3/24/96 at 15:9:54 From: Doctor Steven Subject: Re: Puzzled Well, it really depends on the figures you want to find the area of. The formula for finding the area of a rectangle is side*side. The formula for finding the area of a triangle is (1/2)*base*height. The formula for finding the area of a parabola is (2/3)*base*height. The formula for finding the area of a circle is pi*radius^2. If you want to find the area of a regular polygon, say a hexagon (6 sides), divide it into 6 equal triangles, then find the area of one triangle. The area of the hexagon is 6*(area of triangle). Hope this helps. If you have any more questions feel free to ask. -Doctor Steven, The Math Forum |
