Dear Friends,
I am asking your help to solve this problem in the home work for 4th grade student (elementary school, CA):
"John is making a tile design to cover a rectangle. So far, he has used 2 squares and 2 triangles. How many and what shape tiles could John use to finish his design.
Draw a picture of John's design."
Thank you for your time help.
