## anonymous 3 years ago NEED HELP CUZ MY TEACHER IS A POOPHOLE

1. anonymous

The area of a right triangle is 30mm squared. The height is 12mm. Find the perimetier

2. anonymous

i no im probs stupid for asking dis shizzle

3. anonymous

4. anonymous

I understand perimeter but i just don't get the concept of finding the perimeter with the area and height

5. anonymous

FFirst you have to find the length of the side

6. anonymous

well a right triangel is 90 degrees

7. anonymous

uggg idn thats y i am asking :(

8. anonymous

you know the Pythagorean theory?

9. anonymous

yupper leg squard +leg squared= hypothenus squared

10. anonymous

Pythagorean Theorem In any right triangle, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs. Translated meaning is the long side squared equals the sum of the two other sides squared. use that to find the length of the side

11. anonymous

i understand that so would you do 30 squared + 12 mm= Hyp

12. anonymous

yes

13. anonymous

but i dont understand cuz 30 is the area so its not a leg

14. anonymous

c^2=a^2+b^2

15. anonymous

but 30 sqaured is the area not the leg....

16. anonymous

$\sqrt{30^2 + 12^2 =32.31099}$

17. anonymous

now that you have all the sides of the triangle (30,12,32.31099) use this formula (a+b+c= the perimeter

18. anonymous

I NOOO but isn't 30 the area! sorry i am sassy

19. anonymous

what i thought you wanted to find the perimeter not the area?

22. anonymous

i am saying that 30 is the area not a leg of a right triangle

23. anonymous

ohhhh well then

24. anonymous

The area of a right triangle is 30mm squared. The height is 12mm. Find the perimetier

25. anonymous

you need to find the length of sides

26. anonymous

hold on one sec see if I can find someone to help us figure this out

27. anonymous

You know the area. 1/2*b*h.. you know the height.. find the base.. once you know the base and height.. find the hypotenuse using pyth theorem.. And base, height, hyp.. that gives you the perimeter.

29. yrelhan4

Yeah?

30. anonymous

hey you still there toni??

32. anonymous

@bostonblue

33. anonymous

oo woopshow do u find the base

34. anonymous

@yrelhan4

35. anonymous

All you have to do is multiply the area by 2 and divide it by the height of the triangle. This should give you the base.
