Answer 1

Hello !
______________________________________________________________
The perpendicular on AB name it LP
The perpendicular on AC name it MP
Construct a ray from P to A
Join PA
______________________________________________________________
ar(PAC) = 1/2 X 16 X 3
              = 24 cm²

ar(PAB) = 1/2 X 10 X 6 
              =  30 cm²
_____________________________________________________________
ar(ABC) = ar(PAC) + ar(PAB) 
              = 24 + 30 
              = 54 cm²
