this instructable combines a few mathematical tricks to enable you to calculate the area of irregular shapes. heron’s formula is a way to calculate the area of any triangle, knowing the lengths of it’s three sides, a, b and c. more information can be found at .org/wiki/heron%27s_formula firstly, calculate the semiperimeter. to use heron’s formula on a complex shape, all we have to do is split the shape up into a series of triangles, and measure all the edges. all you have to do is add in values of a,b and c for each triangle, and it will calculate areas and give you a total.edit: i have included versions of the spreadsheet, that have all but the a,b and c cells protected. the advantages of this method are that: – there is nothing saying that the triangles have to all lie in the same plane. if you wanted to measure the surface area of a small 3d shape, you could use string lines to draw triangles over it’s surface, and then measure the length of each edge.

topo maps and surveyed areas give you the first, but on the ground, a bit of undulation can take a 2ha paddock up to a 2.5ha paddock. add the lengths & multiply by the strip width and you have a pretty good approximation of the area. for gardens/areas that are almost circular, using simpson’s method from the centre to measure out arcs (keep the width of the ends constant) and divide the total by two is also a good approach. after using this method for a number of years, i find that if i choose the width of the rectangles correctly, my results are close enough the output of high end digitizers or autocad and don’t take much time to do using a simple measuring wheel and a straight edge. this will give you an odd number of measurements to make.e.g. all you need to do is go for a walk around the paddock with a trundle wheel. i’ve left the unprotected versions in as well, if people want to adapt them.

area of parallelogram or area of irregular shapes (squarefootagearea.com) square footage = square feet = sqft = sq ft = sq ft = ft2 remember, the input can only be in feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m) but never a combination of two different units!. if you have inputs in different units of measurement. now that we know the difference between regular and irregular shapes. then, you can easily calculate the area of each triangle by using the heron’s formula. after calculating area of each triangle, simply add all of them to find the area of an irregular shape.

step 3: press calculate button. the output our calculator provides is independent of the unit of measurement. step 3: divide the drawing into different shapes. step 4: calculate the area of each shape using our square footage calculator. for triangles, multiply the base by the height and then divide by 2. for circles, multiply the radius square by 3.14 (pi). to convert among square feet, square inches, square yards, square centimetres, square millimetres and square meters you can utilize the following conversion table.
