How Find the length of the shortest altitude of a triangle with sides of lengths 13 cm, 14 cm, and 15 cm. Actually Works

Key Insights

Mathematically, the shortest altitude corresponds to the longest side—since altitude decreases as the base increases for a fixed area. With sides 13, 14, and 15 cm, the longest side is 15 cm, so finding the altitude to this base will yield the shortest height.

Start by calculating the triangle’s area using Heron’s formula. Half the perimeter is $(13 + 14 + 15)/2 = 21$ cm. Then the area $A$ is:
$$ A = \sqrt{21(21 - 13)(21 - 14)(21 - 15)} = \sqrt{21 \cdot 8 \cdot
