The second side of a triangular deck is 55 feet longer than the shortest side and a third side that is 55 feet shorter than twice the length of the shortest side. if the perimeter of the deck is 80feet, what are the lengths of the three sides?

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
