what do i do after?

12. qweqwe123123123123111

Here: BR = PO(BN\PQ) Now that you have BR you can find you're perimeter

13. MACmakeuplover

? idk what to do

14. qweqwe123123123123111

I just told you what to do.

23. MACmakeuplover

24. qweqwe123123123123111

@dan815, way to show him how to figure it out for himself, dude.

25. qweqwe123123123123111

Then I would suggest you look the word up. I'll wait while you do that.

you see the 2 pictures are proportional to each other look at the bottom side one of them is 10 the other is 4 This means that 4 * 2.5 = 10 so the one on the left is 2.5 times better now you can solve for x and y and z with that proportion and add up all the sides

27. dan815

2.5 times bigger*

28. MACmakeuplover

ohhhhh thanks :)
