Area Of Triangle = Square Root Of (S(S-A)(S-B)(S-C))

Now S = 5+12+13/2 = 15

Now Simply

Area = Square Root Of (15*10*3*2)

Area = Square Root Of (900)

Area = 30

Now Area Of Triangle = 1/2*Base*Height

Now Base = 13

Now 

1/2*13*Height = 30

13*Height = 60

Height = 60/13 = 4.61 cm

find area using herons formula first, then use 1/2 bh to find h.
if you get the answer, pls like it

VERY GOOD PRAKHAR

ITS VERY SIMPLE JUST PUT HERONS FORMULA AND THEN USE 1/2* BASE *HEIGHT TO FIND H AND PLEASE LIKE

Let's say that the triangle is ABC with AB = 12, BC = 5, CA = 13. Now you may see that triangle is right-angled at B, as AB² + BC² = CA². And AB ⟂ BC with CA as hypotenuse and perpendicular's foot on CA be D. Hence, ar(ABC) = ½ AB · BC = ½ CA · BD. ⇒ BD = ( AB · BC ) ÷ CA = ( 12 × 5 ) ÷ 13 = 60/13 cm
