Answer:
73 km²
Explanation:
split the shape into 3 parts (the triangle on the left, the large rectangle and the little square in top right)
area of triangle = 1/2 X 8 X height.
looking at right side of shape, total height of shape is 2 + 5 = 7.
height of triangle is 7 - 2 = 5.
area of triangle = 1/2 X 8 X 5 = 20.
area of rectangle = 7 X (5+2) = 49
area of square = 2 X 2 = 4
total area = 20 + 49 + 4 = 73 km²
