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.
Area of upper triangle = 1/2 × height × base
= 1/2 × 13 × 24
= 156 m2
Area of lower triangle = 1/2 × height × base
= 1/2 × 8 × 24
= 96 m2
Area of the field = 156 + 96 = 252 m2
