Question

7 times what equals 16.1

Answer 1

The area of a triangle can be calculated using the formula shown below:

$A=\frac{bh}{2}$

Where "b" is the base of the triangle and "h" is the height.

In this case you know the area of the triangle and its base. These are:

$\begin{gathered} A=16.1mi^2 \\ b=7mi \end{gathered}$

Then you can substitute these values into the formula:

$16.1mi^2=\frac{(7mi)h}{2}$

Finally, solve for "h":

$\begin{gathered} (16.1mi^2)(2)=(7mi)h \\ \\ \frac{32.2mi^2}{7mi}=h \\ \\ h=4.6mi \end{gathered}$

The answer is:

$h=4.6mi$
