Ex 11.2, 4 The diagonal of a quadrilateral shaped field is 24 m and the perpendiculars dropped on it from the remaining opposite vertices are 8 m and 13 m. Find the area of the field. Given Length of diagonal = d = 24 m Length of Perpendicular dropped on BD h1 = 13m & h2 = 8 m Now, Area of ABCD = 𝑑/2 (h1 + h2) = 24/2 (13 + 8) = 12 × 21 = 252 Area of quadrilateral = 252 m2
