Answer:

9 square kilometers

Step-by-step explanation:

Let's round the width to 2.0 kilometers, and round the length to 4.5 kilometers.

We know that area is length times width, so

A = lw

A = 2.0*4.5

A = 9.0 square kilometers

If we do this on the calculator, it's around 9.36 square kilometers, so our estimate was good.
