Alex has a small notebook that is shaped like a rectangle . she knows one side is 6 cm and another side is 4 cm .explain how to find the distance around the notebook without using a ruler . need for 2nd grade

20 cm

Step-by-step explanation:

Since it is a rectangle, we know that there are two pairs of sides the same length. All we have to do is add each number by itself, and add those numbers together, or you can envision it like this graph I made.

4+4=8

6+6=12

8+12=20

i think it might be a but you might want a second opinion
