Surveyor's Area Formula Surveyors use a formula to findthe area of a plot of land: If the vertices (x1,y1), (x2,y2),(x3,y3), ., (xn,yn) of a polygon are listed counterclockwisearound the perimeter the area of the polygon isA=1/2x_1x_2;y_1y_2|+|y_2x_3|+|_(y_3)x_...
To find the area of the given polygon, we will break the polygon down into simpler shapes: triangles and trapeziums. We will calculate the area of each shape and then sum them up to find the total area. 1. Identify the Shapes: - The polygon consists of 4 triangles and 2 trapeziums...
How to Find Area of a Rectangle A rectangle is a polygon with four straight sides and four interior right angles. Unlike a square, a rectangle’s adjacent sides have different lengths, but the opposing sides are equal. Thearea of a rectangleis equal to the length times the width. ...
