Answer 1

Same thing as your previous equations, can you set it up and solve for the missing sides?

Answer 2

3.5/21=17/x

Answer 3

how did you come up with that?!

Answer 4

Actually we need to find the length using the perimeter

Answer 5

(2*3.5) + (2*l) = 17

and then use the proportions to find the length of the other paralellogram

Answer 6

my mistake

Answer 7

oh okay so um

Answer 8

lenght = 5

Answer 9

yes and what is the length of the other parallelogram

set up the proportion

Answer 10

3.5/21=5/x so x=30

Answer 11

perimeter=2*30+2*21=102

Answer 12

Good!

now perimeter = 2*l + 2*w

Answer 13

You got it!
