Question

would someone be willing to help me on my last problem? pleaseeeee!!! im really stuckkkk!!!!! and need to get it done!

Answer 1

i just need to find the perimeter and area!

Answer 2

Use the distance formula to find the distance between the 4 adjacent pairs of points.

Answer 3

im not sure how to do that i really stink at geometry

Answer 4

First plot all 4 points on the graph. Then find the points that are connected, and use the distance formula: D = Sqrt((x1 - x2)^2 + (y1 - y2)^2)

Use the formula for all 4 pairs of points that are connected and add up the results.

Answer 5

easy for perimeter, you need to search for norm of the vector \[\sqrt{(x_B-x_A)^2 + (y_B-y_A)^2}\] for distance between point a and point b, now calcul all the sides

Answer 6

i got that but what do i plug into that equation?

Answer 7

Draw all 4 points on your graph paper there. Then find 4 pairs of points that are connected to each other, and use each pair in that equation.

Answer 8

xb= abscissa of point b yb is the ordinate of the point b

Answer 9

?? what

Answer 10

im sorry i dont mean to make things hard

Answer 11

take two vertices in your problem (-1,2) and (4,4) now use the formula, \[\sqrt{(xb-xa)^2+(yb-ya)^2}=\sqrt{(4-(-1))^2+(4-2)^2}\]

Answer 12

If you have two points, (2, 3), (4, 5), then xa=2, ya=3; xb=4, yb=5. So for every pair of points that are connected you plug into that formula.

Answer 13

this is the distance between this two points

Answer 14

But you'll have 6 possible pairs of points, but only 4 are connected. The diagonal distances are not part of the perimeter. so first draw the 4 points on the graph to make sure you're only computing distances for the 4 pairs of points that are connected around the outside.
