 $\begin{array}{r} b = & h \\ h = & b \end{array}$

Step 1

The area of a triangle is equal to $\frac{1}{2}$ the base times the height.

$\frac{1}{2} \cdot (b a s e) \cdot (h e i g h t)$

Step 2

Substitute the values of the base $b = h$ and height $h = b$ into the formula for the area of a triangle.

$\frac{1}{2} h \cdot b$

Step 3

Combine $\frac{1}{2}$ and $h$ .

$\frac{h}{2} \cdot b$

Step 4

Combine $\frac{h}{2}$ and $b$ .

$\frac{h b}{2}$
