Maria walked 3 km west and 4 km south calculate how far she is from her starting point.

5 km

Step-by-step explanation:

We are given the distances walked by Maria;

We are required to determine the displacement from her starting point;

a² + b² = c²

Taking, the distances towards south and towards west as the legs of the triangle;

Then, c² = 3² + 4²

               = 25

         c  = √25

            = 5 km

Therefore, the displacement from the starting point is 5 km

32

step-by-step explanation:

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
