Answer:
2,352 km^2
Step-by-step explanation:
So there is a square and 4 triangles.
You first, find the area of the square.
You then get: 35 x 48 = 1,680
Then you need to add the triangles.
Because we have 2 triangles on each side the area formula of a triangle in which is 1/2 times by the base and height can be solved by just B * H.
Doing that you can get: 48 * 7 = 336
Because you have 2 triangles, the final area results in:
1,680 + 336 * 2 = 2,352
