Question

The diagonal of a quadrilateral shaped field is 42m and the perpendiculars dropped on it from the remaining opposite vertices are 7 m and 12 m. Find the area of the field.​

Answer 1

Answer:

399 m^2.

Step-by-step explanation:

This consists of 2 triangles with a common base.

So the area of the quadrilateral

=  1/2 * 42 * 7 + 1/2 * 12 * 42

= 21*7 + 6*42

= 399 m^2.
