Answer 2

$\huge{ \underline{ \underline{ \mathfrak{ \sf{Heron's \: Formula}}}}}$

Given : 3 sides of the triangle.

One of the side : 10cm

Second Side : 24cm

Third Side : 26cm

Using heron's formula : $\sqrt{s(s - a)(s - b)(s - c)}$

Here, S = The semi perimeter.

The semi perimeter can be found by summing all the 3 sides, and dividing it by 2.

So now, S = $\frac{a + b + c}{2}$

→ $\frac{10 + 24 + 26}{2}$

→ S = 30.

Now substituting the value of s in the equation,

$\sqrt{30(30 - 10)(30 - 24)(30 - 26)}$

$\sqrt{30 \times 20 \times 6 \times 4}$

= $\sqrt{14400}$

= 120 cm²
