What is the area in the given figure (you were even told how to do that)? What would twice that area be? What simple figure would you make to have this new area? Hint: Think rectangle.

Listen this is my son’s study guide. I’m just trying to find the correct way to explain it to him.
What we did first is to count the squares inside the rectangle and then take away the squares in the shaded area.
Then we were not sure so we multiply the shaded area by two.
But I just don’t know if what’s the right way to do it.

The questions I asked are exactly the questions that you should ask you son and have him answer.

If you count the squares there are 11 of them. Double that number and get 22 which will be the new area.

Now decide on any two numbers that multiply out to 22. You can use 1 and 22 or 11 and 2.

If you pick 11 and 2, then make a rectangle that is 11 by 2.

I am sorry that you do not want your son to think. It is great that you are willing to help him, but please understand that thinking is good.

Thanks!! Is not that I don’t want him to think... my son has autism, and he struggles... is hard for him to understand somethings specially because he’s speech delayed. That’s why school is basically for both of us, and I have to rely on what he understood in class in order for me to help him.
Ps: Thanks for making me feel guilty that’s just great! ya know since I have it so easy...
Thanks from topsquark
