Answer:
11.6 km²
Step-by-step explanation:
- Divided it into two shapes, a triangle and a rectangle. Then find the area for each. The triangle is 4 km long and 2.2 km wide. The rectangle is 1.8 km wide and 4 km long.
- Solve the area for the triangle. The equation l · w ÷ 2=A will help. So, the equation would be 4 · 2.2 ÷ 2=4.4
- Then, solve the area for the rectangle by using the equation l · w=A. 1.8 · 4=7.2
- Add them together. 4.4+7.2=11.6
- Final answer - 11.6 km²
