find area of a ideal triangle 3x4x5
The formula for the area of a triangle is
= base×altitude
A 3-4-5 triangle is a right triangle because it
satisfies the Pythagorean theorem:
a˛ + b˛ = c˛
3˛ + 4˛ = 5˛
9 + 16 = 25
25 = 25
So the base is b which is 3, and the altitude is a which is 4.
Substituting into the formula for the area:
A = ×base×altitude
A = ×3×4
A = ×12
A = 6 square units
