## imilee 3 years ago What is the perimeter of the following polygon? 50 units 48 units 47 units 46 units

1. lgbasallote

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

2. imilee

3. lgbasallote

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

4. lgbasallote

|dw:1339668933137:dw|

5. lgbasallote

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. imilee

no i dont im sorry

7. waterineyes

x = 17..

8. lgbasallote

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

9. waterineyes

Perimeter is : 50

10. lgbasallote

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

11. lgbasallote

12. lgbasallote

do you get the solution @imilee ?

13. imilee

No, i have no clue how to

14. lgbasallote

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

15. waterineyes

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

16. lgbasallote

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

17. waterineyes

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. imilee

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. lgbasallote

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

20. lgbasallote

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

21. waterineyes

ok i will take care of it...
