Question

Could some explain how to do this step-by-step please..

Answer 1

If you count the distance from (-3, 2) and (3, 2), you get 6 units. If you count the distance from (-3, 6) and (-3, 2), how many units do you get??

Answer 2

@Trexy Are you there?

Answer 3

Perimeter for Triangle = a + b + c , i.e. sum of all sides..

so from the graph..

1. AB + BC + AC = perimeter for triangle..
2. Name the points, A as (x1, y1) B as (x2 , y2 ) and C as (x3, y3)

3. Find AB, AB = \[\sqrt{(x2-x1)^{2} + (y2- y1^{2}) }\]
4. Similarly find for AB and AC...

5. Put them together in step 1....

and Bingo !!!!!!

Answer 4

Im here.. Im trying to read the steps how to solve it

Answer 5

AB is four units long and BC is 6 units long. Use the pythagorean theorem.

a^2 + b^2 = c^2

4^2 + 6^2 = c^2

16 + 36 = c^2

52 = c^2

7.21 = c

That's your answer! :)

Answer 6

substitute the value of x1, x2, y1 and y2 in step 3..
here x1 = -3, y1 = 6 and x2 = -3 and y2 = 2.. try finding AB.. u will understand for BC and AC.. or else m here..

Answer 7

So i found a site and I put the same thing and the answer is 12.0
this is different right?

Answer 8

@Ganpat

Answer 9

well, You have calculated area.. The figure says...

Look carefully..

Answer 10

ok. thanks

Answer 11

did u understood, how it shd be solved ??

Answer 12

JB said 4^2+6^2=c^2
how did he got that.. @Ganpat

Answer 13

if u look the co-ordinates, then follow this steps,

1. For line AB, consider y co-ordinates, as x does not changes.. so the length AB = 6-2 = 4
2. For Line BC, Consider x co-ordinates, as y does not changes, So length BC = 3- (-3)= 6
3. Hypotanious = BC2 = AC2 + BC2 = sq rt of (36 +16) = sq rt (52) = 7.211

So that was the dimension of Hypotaneous..

Answer 14

So the Perimeter will be, = ab + bc + ac = 6 + 4 + 7.2 = 17.21.. rounding to nearest figure..

Answer 15

gotta ????

Answer 16

So for this one, I have to use distance formula too right?
ifor this one i got 6.40

Answer 17

1. Fox X name points x1 and y1
2. For U name points x2 and y2

3. Use above mentioned formula.. \[\sqrt{(x2−x1)^{2}+(y2−y1)^{2}}\]

U give a try for this, i will message u answer..

Answer 18

answer would be, 6.40.....

Answer 19

yeah I go 6.40

Answer 20

so if you round 2 decimal places 9.05535138
it would be 9.06 or 9.10

Answer 21

it would be 9.05 only..

for the figures like 9.05987, the answer would be 9.06...

Answer 22

anything above five at any place, raise the previous figure by a unit..
