Question

7 times what equals 16.1

Answer 1

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

`A=(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=((7mi)h)/(2)`

Finally, solve for "h":

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

The answer is:

`h=4.6mi`
