Area of a Triangle

Area of a Triangle

How to find the area of a trianle (acute, right, obtuse): formula, examples, and their solutions.

Formula

A = (1/2)*bh. A: area of a triangle, b: base, h: height

A = (1/2)⋅bh

A: area of a triangle
b: base
h: height

Example 1: Acute Triangle

Find the area of the given triangle. base = 6, height = 4.

b = 6, h = 4

A = (1/2)⋅6⋅4

Example 2: Right Triangle

Find the area of the given triangle. base = 5, height = 11.

b = 11, h = 5

A = (1/2)⋅5⋅11

Example 3: Obtuse Triangle

Find the area of the given triangle. base = 8, height = 10.

b = 8, h = 10

A = (1/2)⋅8⋅10
