Answer:
Step-by-step explanation:
Split the quadrilateral into 2 triangles as pictured
One of them is right triangle with 2 sides known
The third side is the hypotenuse and is:
- √(60²+25²) = √4225 = 65 m
Total area is the sum of the areas of the 2 triangles
Area 1
Use Heron's formula for the second triangle:
- A2 = 1/4√(65 + 64 + 27)(-65 + 64 + 27)(65 - 64 + 27)(65 + 64 - 27) ≈ 851m²
Total area
