Shoelace area of polygon

WebAnd we recognise three applications of the Shoelace formula! Denote by AL the polygon area to the left of our chosen triangle; by AR the remaining polygon area; and by A∆ the area of the triangle itself. Then t = AR − AL 2A∆. For our example polygon, again using Pick, AL = 5/2, AR = 8 − 5/2 = 11/2 and A∆ = 5/2. This gives t = (11/2 ... WebVerify the area using the shoelace formula. Calculate the area and perimeter of the given quadrilateral using the shoelace formula. Break up the pentagon to find the area using Green’s theorem. Compare your method with a partner.
