1.) Find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. Round your answer to the nearest tenth. My answer: 312square yards. Is that correct? 2.) Question is: A park in a subdivision is triangular-shaped. Two adjacent sides of the park are 533 feet and 525 feet. The angle between the sides is 53 degrees. Find the area of the park to the nearest square foot. My answer: 111739.09. Is that correct?

find the area of each of the 6 equilateral triangles making up the hexagon Each side of triangle = 12 yards { by the way, first check apothem length because it is our altitude ) tan 30 = (1/2)(12)/apothem apothem = 6/tan 30 = 10.4 - sure enough, whew } so area of triangle = (1/2)(base)(apothem) = .5 * 12 * 10.4 = 62.4 so 6 of them is 6*62.4 = 374 yd^2

question #1 perimeter=6*12=72 yards, so: \[\Large \begin{gathered} area = \frac{{perimeter \times apothem}}{2} = \hfill \\ \hfill \\ = \frac{{10.4 \times 72}}{2} = 374.4 \hfill \\ \end{gathered} \]

question#2 the requested area is: \[\Large Area = \frac{1}{2} \times 533 \times 525 \times \sin 53 = 111,739.0907\]
