determining rectilinear area
: 40m × 20m = 800 m² Rectangle B: 30m × 20m = 600 m² Assuming no overlap, total area = 800 + 600 = 1400 m². Example 3: Using Coordinates for an Irregular Shape Vertices: (0, 0), (10, 0), (10, 5), (5, 10), (0, 5) Applying the shoelace formula yields the exact area of this irregular pen
