Question

find the area of a triangle the length of whose Sides are 18CM 24CM 30CM​

Answer 1

AnswEr :

• Area of the triangle is 216 cm².

⠀━━━━━━━━━━━━━

GiveN :

• Sides of triangle = 18 cm, 24 cm and 30 cm.

To FinD :

• Area of the triangle = ?

SoluTion :

Let's solve this question by using herons formula,

☯ Semi-Perimeter :

➠ S = ( A + B + C) /2

➠ S = (18 + 24 + 30)/2

➠ S = 72/2

➠ S = 36 cm

⠀━━━━━━━━━━━━━

Now,

☯ Area of triangle :

➝ √S(S - A)(S - B)(S - C)

➝ √36(36 - 18)(36 - 24)(26 - 30)

➝ √46656

➝ 216 cm²

$\therefore$ Area of the triangle is 216 cm².
