Area of a Right Triangle

Easy Additional Topics In Math Geometry

A triangle has sides of lengths 7 cm, 24 cm, and 25 cm. Determine the area of this triangle.

You can use the formula for the area of a triangle, which is given by:

$$ ext{Area} =\frac{1}{2} imes ext{base} imes ext{height} $$

Alternatively, you can use Heron's formula, which states:

$$ ext{Area} =\frac{ ext{s}(s-a)(s-b)(s-c)}{s} $$

where $s$ is the semi-perimeter and $a$, $b$, and $c$ are the lengths of the sides of the triangle.
