Find the Area triangle (7)(5)



$\begin{array}{r} b = & 5 \\ h = & 7 \end{array}$

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

$h = 7$ into the formula for the area of a triangle.

$\frac{1}{2} \cdot 5 \cdot 7$

Step 3

Combine

$\frac{1}{2}$ and

$5$ .

$\frac{5}{2} \cdot 7$

Step 4

Multiply

$\frac{5}{2} \cdot 7$ .

Combine

$\frac{5}{2}$ and

$7$ .

$\frac{5 \cdot 7}{2}$

Multiply

$5$ by

$7$ .

$\frac{35}{2}$

$\frac{35}{2}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\frac{35}{2}$

Decimal Form:

$17.5$

Mixed Number Form:

$17 \frac{1}{2}$
