 $\begin{array}{r} b = & 7.14 \\ h = & 7 \end{array}$

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 $b = 7.14$ and height $h = 7$ into the formula for the area of a triangle.

$\frac{1}{2} \cdot 7.14 \cdot 7$

Step 3

Combine $\frac{1}{2}$ and $7.14$ .

$\frac{7.14}{2} \cdot 7$

Step 4
