Step-by-step explanation:
S of ∆ = a+b+c/2
= 18+24+30/2
= 72/2
= 36 cm
Area of ∆ = √S(S-a)(S-b)(S-c)
= √36(36-18)(36-24)(36-30)
= √36 × 18 × 12 × 6
= √46656
= 216 cm2
Area of ∆ = 1/2 × b × h
=> 216 cm2 = 1/2 × 24 × h
=> 216 cm2 = 12h
Therefore, h = 216/12
= 18 cm
Hope it helps :)

AnswEr :
⋆ Refrence of Image is in the Diagram :
• First we will find the Semi Perimeter :
• Calculation of Area of Triangle :
⠀
∴ Hence, Area of Triangle will be 216 cm².
- Base = 24 cm
- Area of Triangle = 216 cm²
- Height = ?
⠀
∴ Height to the base 24 cm will be 18 cm.
