Question

I need HELP! I'm posting a picture on a reply with this but it has to do with writing equations!

Answer 1

This is it!^

Answer 2

for each of the edges of the shape you can constrauct a right angle triangle :

I have drawn 1 of them

You can get the lengths of the dotted sides from the points (y2-y1, and x2-x1)

So then you can use Pythagoras to calculate ethe length of the side of the shape (the hypotenuse of the triangle)

Each side will have a different solution, but all use the same method.

Then add up the 4 sides to get the perimeter of the shape

Answer 3

Will you calculate that one side for me using the formula. Not sure how to start the equation.

Answer 4

What is the length of the line I have drawn

(use the points from your original drawing)

Answer 5

I'm not sure. I'm new to this!

Answer 6

I am not going to give you the answer - if oyu want to work with me on this then do so...


LOOK at your original drwing - it gives the coordinates for the 4 points.

The line I drew in Black above is the difference in y between point M and N

It is not difficult to deduce that from the drawing - take a look at it, and then tell me the length of the line I drew

Answer 7

0? because the difference in why which the two why points were 1 and -1 so the difference would be 0

Answer 8

what is 1 minus (minus 1) ?

Answer 9

*y not why

Answer 10

oh i forgot to keep change change. so 2

Answer 11

OK (also - it is pobvious that the line is not 0 length!)

Now do the same for the length of the horizontal line (difference in x)

Answer 12

-4?

Answer 13

Well - lengths do not really come in - numbers - you can do x2-x1

the answer is 4



So now you have a right angle triangle - you know the 2 short sides

so use a^2+b^2=c^2 to calculate l in my drawing
