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

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

- anonymous

FFirst you have to find the length of the side

- anonymous

well a right triangel is 90 degrees

- anonymous

uggg idn thats y i am asking :(

- anonymous

you know the Pythagorean theory?

- anonymous

yupper leg squard +leg squared= hypothenus squared

- 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

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

- anonymous

yes

- anonymous

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

- anonymous

c^2=a^2+b^2

- anonymous

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

- anonymous

\[\sqrt{30^2 + 12^2 =32.31099}\]

- anonymous

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

- anonymous

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

- anonymous

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

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

- anonymous

ohhhh well then

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

- anonymous

you need to find the length of sides

- anonymous

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.

- yrelhan4

Yeah?

- anonymous

hey you still there toni??

- yrelhan4

Add*

@bostonblue

- anonymous

oo woopshow do u find the base

- anonymous

@yrelhan4

- 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.
