A square has all 4 sides equal, so divide the amount of fence available by 4 to get the length of one side of the square

600/4 = 150

Now since the creek is being used for one side, add one side of the square to the other side to get a rectagle 150 by 300 feet.

Area = 150 x 300 = 45,000 square feet.

Find the area round to two decimal places as needed

Mademuasel [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.
