Question

why the area of triangle equal to 1/2 ×b×h explain me anyone?​

Answer 1

Hey there!

We know that,

area of parallelogram is ( base × height )

Also, we know that, diagonal of parallelogram divide it into two ∆s which are equal in area.

So, ar∆ABC = ar∆ADC

So we can write as :

area of ||gm = 2ar∆ABC

=> Ar ∆ABC = area of ||gm/2 = ½ × area of ||gm

$\therefore$ area of ∆ = 1/2 × base × height.
