Question

find the height of the parallelogram ​

Answer 1

First find the area of ABC using

$\frac{1}{2} \times (x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2))$

Similarly find the area of ADC

Add area of ABC and ADC

You will get the area of parallelgram

Find the length of AB using distance formula

Substitute length of AB in

$b \times h = area \: of \: parallelogram$

You will get the value of h that is height
