have you tried adding all the sides? perimeter means sum of all sides..

|dw:1339668880511:dw| if 16 is the base that means the two smaller lines are 8 each

|dw:1339668933137:dw|

now use pythagorean theorem to find x $x = \sqrt{15^2 + 8^2}$ $x = \sqrt{225 + 64}$ do you have a calculator? i dont

6. anonymous

no i dont im sorry

7. anonymous

x = 17..

8. anonymous

it seems $x = \sqrt{289}$ $x = 17$ i remembered lol

9. anonymous

Perimeter is : 50

10. anonymous

|dw:1339669078571:dw| now add 17 + 17 + 16

12. anonymous

do you get the solution @imilee ?

13. anonymous

No, i have no clue how to

14. anonymous

how to what? how to add 17 + 17 + 16?

15. anonymous

Sorry, lgbasallote what do you mean by why you back your answers up??

16. anonymous

i meant don't just give answers...back them up with solutions ;)

17. anonymous

You are giving the solutions, so I thought I can give answers so that it becomes easy for the person who has asked the question..

18. anonymous

SO the answer is 50...... ok all you guys had to say is what i needed to doooo..... 17+17+16. Thank for helping you two :)

19. anonymous

for future note i think it's best if the askers get the answers by themselves ;) answers usually distract them from the solution

20. anonymous

@imilee how 17 was got is pretty important too ;)

21. anonymous

ok i will take care of it...
