No, Height 10
Base 6

Area = \(\frac{1}{2}*6*10=30\)

(-2,-3) and (4,-3) is a straight line parallel to x axis at y=-3. Therefore let's take this as the base..so Base = 4-(-2)=4+2=6..

Now the third vertice is (28,7)..
If we are taking base as parallel to x-axis , the height will be parallel to y-axis.
Therefore height is 7-(-3)=7+3=10

Area will be \(\frac{1}{2}*6*10=30\)

Is it parallel to y axis or x axis? Please make it clear.

y=-3 will be parallel to z-axis.
