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:

$A=\frac{b\cdot h}{2}$

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

$\begin{gathered} A=\frac{7\cdot8}{2} \\ A=\frac{56}{2} \\ A=28mi^2 \end{gathered}$

The area of the triangle is 28 square miles.
