Question

Compute the area of a triangle with sides: 10 x 10 x 16.

Answer 1

To find the area of this triangle, we may use Heron's formula:
A = sqrt ((s)(s - a)(s - b)(s - c))
where s is the semi - perimeter, a, b, and c are the measure of the sides.
s = (a + b + c) / 2 = (10 + 10 + 16) / 2 = 18
Substituting this to the equation for area,
A = sqrt ((18)(18 - 10)(18 - 10)(18 - 16))
A = 48 units²
