The method used for irregular shaped areas is called the "offset method". First measure the length of the longest axis of the area (line AB). This is called the length line. Next, divide the length line into equal sections, for example 10 ft. Area Formulas of Simple Shapes
Rectangle Area
total area = lw
Where l is length and w is width
Triangle Area
total area = (s(s-x)(s-y)(s-z))½
where s = ½(x + y + z)
Trapezoid Area
total area = ½(w1 + w2)h
Where h is the height and w1 and w2 are the top and bottom edge length
Circle Area
total area = πr2
Where r is the radius
Sector Area
total area = ½(θ/π)r2
Where r is the radius and θ is the angle
Ellipse Area
total area = πab
Where a and b are the length of the major and minor axes
Parallelogram Area
total area = bh
Where h is the height and b is the base length
