Question

While finding area of triangles in coordinate geometry chapter,
sometimes we get area in NEGATIVE values Then what should we
do?(example is in the pic)
∆ B C D x 1 = 3   ,   x 2 = - 3   ,   x 3
= 2 y 1 = - 2   ,   y 2 = - 5   ,   y 3 ∆
= 3 A r e a = 1 2 x 1 y 2 - y 3 + x 2 y 3 - y 1 + x 3 y 1 - y 2
                  = 1
2 3 - 8 + - 3 5 + 2 3            
      = 1 2 - 24 - 15 + 6      
              = - 33 2   u
n i t 2

Dear student,

In such answers we neglect the -ve sign of the answer as the area
can't be -ve
