Question 887485
height, {{{-8+b}}} using b for base length.
{{{(1/2)b*(b-8)=154}}} using formula for area of a triangle.


You can solve for the base b, in that equation; and you will also be able to compute the height.



{{{b^2-8b=308}}}
{{{b^2-8b-308=0}}}
Discriminant is {{{1296}}}, {{{36^2}}}.  You can factor if you want to solve...
But...
{{{b=(8+- 36)/2}}}
The one that makes any sense is {{{highlight(b=22)}}}.
