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

questioncovebot2:

3.5/21=17/x

Florisalreadytaken:

how did you come up with that?!

AZ:

Actually we need to find the length using the perimeter

AZ:

(2*3.5) + (2*l) = 17 and then use the proportions to find the length of the other paralellogram

AZ:

my mistake

questioncovebot2:

oh okay so um

questioncovebot2:

lenght = 5

AZ:

yes and what is the length of the other parallelogram set up the proportion

questioncovebot2:

3.5/21=5/x so x=30

questioncovebot2:

perimeter=2*30+2*21=102

AZ:

Good! now perimeter = 2*l + 2*w

AZ:

You got it!
