Question

Find the perimeter of the shape below:

Answer 1

well.. what would be the perimeter of that shape?

what does "perimeter" mean anyway?

Answer 2

the length of each side added together

Answer 3

alrite... then...notice the coordinates of each of those points
you have four points... so.. one sec

Answer 4

Its an even two, If you add -2, -1, -1 and a 2 it gets an even two. The negatives added up should equal 4, then its like taking away a 2 so, that leaves you with 2.

Answer 5

Here are the answers:
7.4
8.9
11.2
13.6

Answer 6

so.. you have four points, S, R, U, T

so, find their distance, notice their coordinates
\(\textit{distance between 2 points}\\ \quad \\
\begin{array}{rrlllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&S({\color{red}{ -2}}\quad ,&{\color{blue}{ 7}})\quad
% (c,d)
&R({\color{red}{ -1}}\quad ,&{\color{blue}{ 3}})\\
&R({\color{red}{ -1}}\quad ,&{\color{blue}{ 3}})\quad
% (c,d)
&U({\color{red}{ -1}}\quad ,&{\color{blue}{ 5}})\\
&U({\color{red}{ -1}}\quad ,&{\color{blue}{ 5}})\quad
% (c,d)
&T({\color{red}{ 2}}\quad ,&{\color{blue}{ 5}})\\
&T({\color{red}{ 2}}\quad ,&{\color{blue}{ 5}})\quad
% (c,d)
&S({\color{red}{ -2}}\quad ,&{\color{blue}{ 7}})\\

\end{array}\qquad
% distance value
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

Answer 7

and them sum them up, to get the perimeter

Answer 8

then rather

Answer 9

I got 14.1

Answer 10

But that is not an answer

Answer 11

please help

Answer 12

14.1 hmmmmm lemm

what did you get for say the SR distance anyway?

Answer 13

hold on I did something wrong

Answer 14

I got 4 for the distance on SR

Answer 15

ok... what did you get anyway?

Answer 16

ugh i messed up agian

Answer 17

I got 13.6 which is the last answer

Answer 18

thank you

Answer 19

is that the correct answer

Answer 20

hmmm ok.. what did you get for SR though?

Answer 21

4.12

Answer 22

not 4

Answer 23

and i got 2 for RU and 3 for UT and finally 4.5 for TS

Answer 24

13.6 is correctt for the perimeter :)

Answer 25

\(\bf \sqrt{17}+\sqrt{20}+2+3\implies 13.6\)

Answer 26

4.12+2+3+4.5=13.62 which rounds to 13.6

Answer 27

yes the square root of 17 is about 4.12 and the square root of 20 is about 4.5

Answer 28

i got the question correct thank you for your help

Answer 29
