Question

Find the area round to two decimal places as needed

Answer 1

To find the area of an obtuse triangle you have to multiply the base of the triangle by the vertical height and divide the result by 2 following the formula:

`A=(b\cdot h)/(2)`

The base of the triangle is b= 7 miles and the height is h= 8 miles, using these lengths calculate the area as follows:

`\begin{gathered} A=(7\cdot8)/(2) \\ A=(56)/(2) \\ A=28mi^2 \end{gathered}`

The area of the triangle is 28 square miles.
