## tonipoo610 2 years ago NEED HELP CUZ MY TEACHER IS A POOPHOLE

1. tonipoo610

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

2. tonipoo610

i no im probs stupid for asking dis shizzle

4. tonipoo610

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

FFirst you have to find the length of the side

6. tonipoo610

well a right triangel is 90 degrees

7. tonipoo610

uggg idn thats y i am asking :(

you know the Pythagorean theory?

9. tonipoo610

yupper leg squard +leg squared= hypothenus squared

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. tonipoo610

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

yes

13. tonipoo610

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

c^2=a^2+b^2

15. tonipoo610

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

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

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

18. tonipoo610

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

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

22. tonipoo610

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

ohhhh well then

24. tonipoo610

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

you need to find the length of sides

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

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?

hey you still there toni??

@bostonblue

33. tonipoo610

oo woopshow do u find the base
