But there is mistake also.

Hope you will correct that..

yes .. please tell

Example 2 has all the units in meters..

but you have found area in cm^2..

Be careful..

84 m^2 will come there..

Answer 31

oh yes units matters a lot ... i will correct it now thanks a lot waterineyes

Answer 32

Welcome dear..

Answer 33

wooh not a big diff. but yes thanks

Answer 34

vry nice @mathslover

Answer 35

thanks @AravindG

Answer 36

one doubt:which is more general "heron's formulka" or 1/2bh?

Answer 37

Of course, 1/2 b h.

Answer 38

so both formula can be used for any triangle??

Answer 39

But if you know what height and base are ..

Answer 40

Yes, but I do prefer using Heron's if you know the side lengths.

Answer 41

without knowing the height

Answer 42

Finding the base and height is tedious in some cases, so...

Answer 43

i seee

Answer 44

It depends upon conditions..
if you are given with height and base then 1/2 bh

If you are given with sides lengths then Heron's Formula..

Answer 45

Yep, that is what I mentioned.

Answer 46

well waterineyes is right it depends on condition

Answer 47

I am just mentioning what you mentioned..
Ha ha ha..

Afterall you are faster than me..

@vishweshshrimali5

Answer 52

Hey guys i want to mention one thing : there are 2-3 errors in the ppt, please neglect them ..

I will post the correct ppt later. .. sorry for that

Answer 53

I was complimenting mathslover how her demonstration came close to still images. must've been tedious drawing all those

Salman Khan has a good video demo on this one also. http://www.khanacademy.org/math/geometry/triangles/v/part-1-of-proof-of-heron-s-formula

but this has the most work -

i have a doubt @mathslover is this formula for every type of triangles ?

Answer 63

yes

Answer 64

then why there are other formulas to find the areas of equilateral triangles etc. ?

Answer 65

they are to make the process easy :

see the ppt again i had proved the formula for finding the area of an equi. triangle by using heron's formula

Answer 66

k!
