Thanks

still works in 2020 thnx guys

2022 correct!

i suggest using h t t p s : / / w w w .symbolab.com/solver/triangle-area-perimeter-calculator/triangle%2C%20find%20Height%2C%20given%20Area%3D110%2Cb%3D10

area of ||gram = (1/2)(a+b)(height), where a and b are the parallel sides


246 = (1/2)(a+b)(20.5)
a+b = 24

So all we know is that the two parallel sides add up to 24, so
not enough info
