\begin{matrix} b = & 3 h = & 5 \end{matrix}

$\begin{array}{r} b = & 3 \\ h = & 5 \end{array}$

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

$b = 3$ and height

$h = 5$ into the formula for the area of a triangle.

$\frac{1}{2} \cdot 3 \cdot 5$

Step 3

Combine

$\frac{1}{2}$ and

$3$ .

$\frac{3}{2} \cdot 5$

Step 4

Multiply

$\frac{3}{2} \cdot 5$ .

Step 4.1

Combine

$\frac{3}{2}$ and

$5$ .

$\frac{3 \cdot 5}{2}$

Step 4.2

Multiply

$3$ by

$5$ .

$\frac{15}{2}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\frac{15}{2}$
