Question 1134783

an equilateral triangle has all sides equal in length

if side is {{{a}}}, perimeter is {{{P=3a}}}

 in order for the perimeter to be greater than {{{45m}}}, we have

{{{3a > 45m}}}

{{{a > 45m/3}}}

{{{a > 15m}}}

the sides of an equilateral triangle must be longer than {{{15m}}}
