 $\begin{array}{r} b = & 5 \\ h = & 1 \end{array}$

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 $b = 5$ and height $h = 1$ into the formula for the area of a triangle.

$\frac{1}{2} \cdot 5 \cdot 1$

Step 3

Combine $\frac{1}{2}$ and $5$ .

$\frac{5}{2} \cdot 1$

Step 4

Multiply $\frac{5}{2}$ by $1$ .

$\frac{5}{2}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\frac{5}{2}$

Decimal Form:

$2.5$

Mixed Number Form:

$2 \frac{1}{2}$
