if the length of the base of a triangle a is twice it's perpendicular height h, we have
a=2h.......eq.1
and if it's area is 36cm%5E2, we have
%281%2F2%29a%2Ah=36.......eq.2
substitute a from eq.1
%281%2F2%292h%2Ah=36
%281%2Fcross%282%29%29cross%282%29h%5E2=36
h%5E2=36
h=6
go to
a=2h.......eq.1, substitute h
a=2%2A6
a=12

answer: it's length is 12 and perpendicular height is 6
