Answer:
250m^2
Explanation:
Area of quadrilateral = ½ × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices
We can substitute the numbers given into the formula shown above.
1/2 * 25 * (8+12)m^2
This can be simplified to 1/2 * 25 * 20 which is 250m squared
