 $\begin{array}{r} b = & 5 \\ h = & 1.9 \end{array}$

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 $h = 1.9$ into the formula for the area of a triangle.

$\frac{1}{2} \cdot 5 \cdot 1.9$

Step 3

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

$\frac{5}{2} \cdot 1.9$

Step 4

Multiply $\frac{5}{2} \cdot 1.9$ .

Step 4.1

Combine $\frac{5}{2}$ and $1.9$ .

$\frac{5 \cdot 1.9}{2}$

Step 4.2

Multiply $5$ by $1.9$ .

$\frac{9.5}{2}$

Step 5

Divide $9.5$ by $2$ .
