Answer:

A. 289 km²

Step-by-step explanation:

Your composite figure is a rectangle on top of a triangle.

The formula for the area of a rectangle is A = lw.

The formula for the area of a triangle is A = ½bh.

The formula for the total area is

A = lw + ½bh.

Data:

 l = 17 km

w = 13 km

b = 17 km

h = 8 km

Calculation:

A = 17 × 13 + ½ × 17 × 8 = 221 + 68 = 289 km²

The area of the figure is 289 km².
