Answer:
123.948 km²
Step-by-step explanation:
We can use the equation: AΔ = 1/2*ab*sinθ, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.
Plugging in the numbers we know, we get: AΔ = 1/2*22*24*sin(28°)
Simplify: AΔ = 264*.4695 (0.4695 is approximately sin(28°))
Simplify: 123.948 km²
