By using the scale tool on Google Earth and filling in this formula, it's easy to find (very closely at least) the area of geographical locations which interest you. Find the area of the quadrilateral whose vertices, taken in order, are (– 4, – 2), (– 3, – 5), (3, – 2) and (2, 3). Davneet Singh is a graduate from Indian Institute of Technology, Kanpur.
Because, the area of the quadrilateral is never negative. Heights, \(h_{1} = 5\) cm & \(h_{2} = 7\) cm, Sum of the heights of the triangles = h1 + h2 = 5 + 7 = 12 cm, \(= \frac{1}{2} \times \; diagonal \times (Sum \; of \; height \; of \; two \; triangle)\). See, First, you must find lengths of each of the quadrilateral's four sides. Area of Quadrilaterals DRAFT. Finding area ∆ ADC
Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices. Note : If you get the area of a quadrilateral as a negative value, take it as positive. of the quadrilateral ABCD in order (counter clockwise direction) and write them column-wise as shown below.
