The height of a triangle is 6 m more than twice the length of the basehighlight%28x%29.
The area of the triangle is 28 m^2 = L*H
x(2x+6) =28
2x^2 + 6x -28 = 0
x^2 + 3x -14 = 0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-3+%2B-+sqrt%28+65%29%29%2F%282%29+ = (-3 +8.06)/2 = 2.5 rounded to 1 decimal point (throwing out neg solution for unit measure
length = 2.5m, height is 11m
I'm LAZY,I got this from https://www.algebra.com/algebra/homework/Triangles/Triangles.faq.question.619188.html

@bookerdana Except the area isn't 28...
@bookerdana At least you tried lol
