## twilaswift Group Title The perimeter of the rectangle is fifty-four feet. What is x? A rectangle is shown. The length is labeled fifteen feet and width is labeled x. thirty-nine feet twenty-seven feet twenty-four feet twelve feet one year ago one year ago

i need the picture to figure it out :|

2. ParthKohli Group Title

The formula for the perimeter is $$P =2(\rm length + width)$$.

3. ParthKohli Group Title

Since the length is $$15$$ and the width is $$x$$, we have this equation:$2(15 + x) = 54$Solve for $$x$$.

5. bloodrain Group Title

ok figure it out based on the info parth gave (unless you want me to explain more)

6. bloodrain Group Title

would you like more explanation?

7. twilaswift Group Title

8. ParthKohli Group Title

OK, so do you know that the perimeter is the sum of ALL sides?

9. ParthKohli Group Title

Notice that opposite sides in a rectangle are equal.|dw:1357571260853:dw|

10. ParthKohli Group Title

So the sum of sides will be $$15 + 15 + x + x$$. But it is also given that the sum of all sides (perimeter) is $$54$$.

11. twilaswift Group Title

Ok.

12. ParthKohli Group Title

So solve the equation $$15 + 15 + x + x = 54$$?

13. bloodrain Group Title

I have to go study for exams for a few min, so let parth finish =3

14. twilaswift Group Title

You have to figure out what x is, right?

15. ParthKohli Group Title

Yes! =)

16. twilaswift Group Title

OK so you divide 15 right?

17. bloodrain Group Title

I can't get on my study page o_o no don't divide by 15 subtract 15+15 from the perimeter and then divide by 2

18. bloodrain Group Title

19. twilaswift Group Title

7.2?

20. bloodrain Group Title

no i think you did it wrong let me try

21. bloodrain Group Title

54-30=? then divide ? by 2 to get answer

22. twilaswift Group Title

11

23. bloodrain Group Title

o_o no, sorry but very close

24. twilaswift Group Title

12

25. bloodrain Group Title

yes :D

26. bloodrain Group Title

how did you get 11?

27. bloodrain Group Title

just wondering

28. twilaswift Group Title

22 divided by 2

29. bloodrain Group Title
