Answer:
P = 40.4 km
A = 90 sq km
Step-by-step explanation:
Perimeter means the distance all the way around a shape.
They only gave two sides but since it is a parallelogram the opposite sides are the same measure. Add up all the sides.
P = 11.2 + 9 + 11.2 + 9
P = 40.4
The area of a parallelogram:
A = base × height
A = 9 × 10
A = 90 sq km
