Question 149348
Let "s"= 2 equal sides, and "b' = base
Since the sides are 6cm longer than the base, "s= b+6"
For the perimeter, we get the measurements of 2 equal sides + the base,
{{{P= 2s + b }}}
{{{45cm = 2(b+6) + b}}}
{{{45 = 2b + 12 + b}}}
{{{45 - 12 = 3b}}}
{{{(33/3) = b}}} ----------- > {{{b= 11cm}}}, base of the triangle
FYI, the sides will be {{{s= 11 + 6}}} ----> {{{s= 17 cm}}}, 2 equal sides
To check,
{{{P= 2s + b}}}
{{{ 45cm = (2*17) + 11 }}}
{{{45cm = 34 + 11 }}}
{{{45cm = 45cm}}}
Thank you
