Answer 3

negative 3, 4 means (-3,4)?

Answer 4

ok

Answer 5

J (-3,4)
K (-1,6)
L (1,1)
M (-1,3)
You can plot a graph of them to guide you.

Then you should calculate the vectors,

JK=K-J

KL=L-K

LM=M-L

MJ=J-M

And then calculate the modulus of each vector. This will give you the length you need to find the perimeter. Try it.

Answer 6

What do u mean by vectors

Answer 7

Well, if you don't know vectors, then you should find an alternative way. For example, plot the figure in a graph, and use the pithagorean theorem to find the length of each side.
