                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.

Answer:

                Area of the field \[=\frac{24\times (8+13)}{2}\] \[=\frac{24\times 21}{2}\] \[=12\times 21\] \[=252\,{{m}^{2}}\].
