Hi,
Re reply, dot between b and h just used as a 'reminder' it is
multiplication. Algebraically, bh says the same thing.
right angled triangle of which the base is 13 times the height
Let x and 13x represent the height and base respectively
A = {{{(1/2)b*h = (1/2)13x*x = 216cm^2}}}
                    x = {{{+sqrt((216*2)/13)}}}
