Answer 1

Answer:

A = 1/2*6*2.57 = 7.71 km²

Answer 2

Answer:

• 7.71 km²

Step-by-step explanation:

Area of triangle:

• A = 1/2bh

We have the value of b but not h.

Added auxiliary segments which help to find the value of h.

See attached for details

• sin 40° = h/4
• h = 4 sin 40°
• h = 2.57 km

The area is:

• A = 1/2*6*2.57 = 7.71 km²
