# The area of a triangle whose base is $b$ and whose altitude is $h$ is $A=$ _________.

The area of the triangle is $A=\frac{1}{2}bh$.

See the step by step solution

## Step 1. Given information.

It is given that,

Base of the triangle$=b$

Height of the triangle$=h$

We need to find the area of the triangle.

## Step 2. Determine the area of the triangle.

Area of a triangle is:

$A=\frac{1}{2}×\text{Base}×\text{Height}$

Substitute the given values in the above formula to find the area of the triangle.

$\begin{array}{rcl}A& =& \frac{1}{2}×b×h\\ A& =& \frac{1}{2}bh\end{array}$

## Step 3. Conclusion.

The area of the triangle is $\begin{array}{rcl}A& =& \frac{1}{2}bh\end{array}$.
