How do you find the area of a square?

i have no idea.........

3. Mertsj

Do you know what a square is?

a figure with 4 equal sides?

5. Mertsj

And 4 right angles.

7. Mertsj

Count the squares. What is the area?

160

is the area

10. Mertsj

Count again

there are 16 squares but the question states that there is an area of 160...

12. Mertsj

Forget about the question. We'll get to that. I'm trying to teach you how to find the area of a square.

oo ok then yea there are 16 squares within the square

14. Mertsj

And that it the area of that square. Now here is another one. tell me its area.

17. Mertsj

So how do you find the area of a square?

by multiplying the length and he width

19. Mertsj

Which, in the case of a square, are the same thing. So you can find the area of a square by squaring one of the sides. Are you with me?

yea i am

21. Mertsj

Good for you. Now let's get to your problem. You have a square whose area is 169

22. Mertsj

|dw:1332355801584:dw|

23. Mertsj

Could the sides be 10?

so u divide 169 by 4? and no they could not be 10

25. Mertsj

Why not?

because 10 * 10 = 100

27. Mertsj

Exactly. Is 10 to big or too little?

the answer to the question is 13 squared....

aint it?

30. Mertsj

13 squared is 169. Is 169 times 169 equal to 169?

no

32. Mertsj

|dw:1332356009521:dw|

33. Mertsj

Then the answer cannot be 13 squared.

your right its just 13 inches i read the problem wrong thank you for being so patient with me!
