Okay sy mash members we've got a lovely little triangle

00:05

for you here and it's a special ones you khun

00:07

tell We got eight and then sixteen sixteen so it's

00:09

i sasa lease and a couple other things alright question

00:12

The triangle shown above is dilated by a factor of

00:14

three Yeah it's giving birth What is its perimeter After

00:18

the transformation Perimeter after dilation Well if we drew a

00:27

triangle on a balloon and inflated it the triangle would

00:30

be stretched out which essentially what happens with a dilation

00:35

tried out Just don't get blue in the face from

00:38

blowing up the balloons In this case strangles dilated by

00:40

a factor of three which means all sides become three

00:43

times as long was multiplying All three right so three

00:46

times sixteen forty eight three times sixteen Still forty eight

00:49

three times eight is twenty four right so we could

00:52

just add all those up or if we were a

00:54

little bit more clever we could have just added the

00:56

sixteen sixteen to thirty two and a that's forty Multiply

00:59

it by three and you get one twenty and that's

01:01

it The answer is c as in the simulator we

01:04

came we shmoop
