Hey.....

From second last step :
1/2 |-1 +0 - 1|
= 1/2 *| - 2|
= 1/2 *2 = 1

When modulus is removed than the answer becomes positive so it would be +2 instead of - 2....

Hasti152002: the bracket ([) which u have done in pic... instead of that modulus (|) will come in the formula of area of triangle...
