Answer:
Area Of Triangle will be 6
= 1/2*base*height.
=1/2*4*3
=1/2*12
=6
and by geometric mean.
BD will be....
BDsquare= AD*DC
= 2.5*2.5
= 6.25
therefore BD WILL BE 2.5cm

Answer:
Answer is 2.4cm
Step-by-step explanation:
s = a+ b+ c/2 = 3+4+5/2= 12
under root s × s- a × s-b ×s-c
= 12× 12-3×12-4×12-5 = 55
So, area of ABC is 55cm^2
Now,
1/2× b×h = 55
1/2×5× h =55
2.5× h = 55
h= 55/2.5= 550/ 25 = 2.4
h = 2.4 cm
