Question

Find the perimeter of the shape below:

(attached)

7.4 units

8.9 units

11.2 units

13.6 units

Answer 1

to get the perimeter add all the lengths going around the shape.
you can use the distance formula (pythagorean theorem) to calculate the lengths not given

Answer 2

Okay....
TU + UR + RS + ST

Answer 3

TU + UR + RS + ST


the TU and UR are obvious.

RS, 1²+5²=(RS)²
ST, 2²+4²=(ST)²

Answer 4

3 + 2 + √26 + √20

Answer 5

you got it from here.

Answer 6

Very confused but thanks anyways

Answer 7

how are you confused, what's not clear? Ask please...

Answer 8

My bad actually for Sr, it is 1²+4²=(SR)²

Answer 9

TU + UR + RS + ST

3 + 2 + √17 + √20

Answer 10

Sorry for the mistake

Answer 11

ut = 4
st = rt of (4^2 + 2^2)
ur = 2
sr = rt of (4^2 + 1^2)
perimeter = st + tu + ur + rs

Answer 12

ok i got 13.6

Answer 13

is that right?

Answer 14

sorry ut should be 3 not 4

Answer 15

Oh okay, so it's 13.6?

Answer 16

3 + rt 20 +rt 17 + 2 = 4.47 + 4.12 + 5 = 13.59 = yes
