Q6 of 33 Page 12

The area of a quadrilateral is 360 m2 and the perpendiculars drawn to one of the diagonal from the opposite vertices are 10 m and 8 m. Find the length of the diagonal.


In the given Fig. AE = h1 = 8 cm
CF = h2 = 10 cm and area of quadrilateral ABCD = 360 m2
Area of a quadrilateral = (Diagonal)(h1 + h2)
                           360 =  ´ DB ´ (10 + 8)
                            � = 40 m
