Question

Plot points A(-3,2) B(4,2) C(2,-3) and D(-5,-3) Find its area and perimeter. PLS HELP ME

Answer 1

i find it might make things simpler by "moving" this so that one of the points is at the origin; helps me to see the the shapes better

Answer 2

Plot the points according to your knowledge of coordinate system and then detect what figure is that whether it is square, rectangle or some other one.

Answer 3

Use distance formula for calculating side's distances

Answer 4

ITS A PARALLELOGRAM

Answer 5

since it feels to me that -5,-3 is the farthest away, ill adjust all the points by that

A(-3,2) B(4,2) C(2,-3) D(-5,-3)
5 3 5 3 5 3 5 3
------------------------------
2 5 9 5 7 0 0 0

Answer 6

If it is a parellelogram then use the formula for finding area of it :

base * corresponding height.

Answer 7

what is the base and height? pls help :(

Answer 8

Take any side as base and then decide the corresponding height. Wait lemme draw a diagram.

Answer 9

A(-3,2) B(4,2) C(2,-3) D(-5,-3)
5 3 5 3 5 3 5 3
------------------------------
2 5 9 5 7 0 0 0
^________^ ^-------^
5 high 7 wide

Answer 10

ok :) thanks for the hep :)

Answer 11

A(-3,2)
5 3
-----
2 5
^^^^ this is our offset, so that the slant length can be determined using pythag

Answer 12

thanks for all the help :)

Answer 13

(It depends what side you consider as base ) --- Amistre is explaining well. Follow him :)

Answer 14

uhm, I can't understand it very well, how can I find out the base and the height if there are coordinates?

Answer 15

2 5 9 5

0 0 7 0

a skewed rectangle retains the same area

Answer 16

the base and height can be better seen by positioning this thing at the origin ... at least thats the simplest way i can see it

Answer 17

the corrdinants given correspond to:

2 5 9 5
||height is from 0 to 5
0 0 7 0
-------
base is from 0 to 7

Answer 18

bad formatted lol

2 5 /
/ the slanted side has a length of a 2,5 rt triangle
0 0 / to fiinsh with the perimete

Answer 19

we already have enough information for the area, can you tell me what you think it would be?

Answer 20

10? i really don't know im just in middle school :(

Answer 21

the area corresponds to the "rectangle" of the same proportions.

do you recall how to find the area of a rectangle?

Answer 22

W X H

Answer 23

correct, since the width is 7 and the hieght is 5 .... we can determine the area

Answer 24

35? :) but how did youu know that 7 is the width and 5 the height?
