Answer 2

To calculate the area (S) of a triangle using Heron's formula, you need to know the lengths of its three sides (a, b, and c). Given that a=1, b=3, and c=5, we can proceed to find the area.

Heron's formula for the area (S) of a triangle with side lengths a, b, and c, and semi-perimeter (p) is given by:

S = √(p * (p - a) * (p - b) * (p - c))

where p = (a + b + c) / 2

Let's calculate the semi-perimeter (p) first:

p = (1 + 3 + 5) / 2 p = 9 / 2 p = 4.5

Now, substitute the values of p, a, b, and c into Heron's formula to find the area (S):

S = √(4.5 * (4.5 - 1) * (4.5 - 3) * (4.5 - 5)) S = √(4.5 * 3.5 * 1.5 * (-0.5)) S = √(4.5 * 3.5 * 1.5 * 0.5) (since -0.5 * -1 = 0.5) S = √(11.8125) S ≈ 3.44

So, the area of the triangle with side lengths a=1, b=3, and c=5 is approximately 3.44 square units.
