Question 909609
An isosceles triangle has two legs of equal length.
The perimeter is 16", which is the base + both legs.
The base = 1/4x the length
L = 4B
B + 2L = 16
B +2(4B) = 16
9B = 16
B = {{{16/9}}}
If the base is {{{16/9}}}, then the lengths are {{{64/9}}}
{{{16/9}}}+{{{64/9}}}+{{{64/9}}}= {{{144/9}}} or 16
