Question -
Answer -
BL and CM are drawnperpendicular to x-axis.
It can be observed inthe following figure that,
Area (ΔACB) = Area(ALBA) + Area (BLMCB) – Area (AMCA) … (1)
Equation of line segmentAB is
Equation of line segmentBC is
Equation of line segmentAC is
Therefore, from equation(1), we obtain
Area (ΔABC) = (3 + 5 –4) = 4 units
