To find the area of a triangle with side lengths of 24cm, 30cm, and 18cm, you can use Heron's formula.
Heron's formula states that the area (A) of a triangle with side lengths a, b, and c can be calculated using the formula:
A = √(s(s-a)(s-b)(s-c))
where s is the semi-perimeter of the triangle, calculated as:
s = (a + b + c) / 2
In this case, the side lengths are a = 24cm, b = 30cm, and c = 18cm.
Calculating the semi-perimeter:
s = (24 + 30 + 18) / 2
s = 72 / 2
s = 36
Substituting the values into Heron's formula:
A = √(36(36-24)(36-30)(36-18))
A = √(36 * 12 * 6 * 18)
A = √(46656)
A ≈ 216 cm²
Therefore, the area of the triangle with side lengths 24cm, 30cm, and 18cm is approximately 216 cm².
