Question 1197003

let the side of square be {{{a}}}

the perimeter will be {{{P=4a}}}


if each side of the triangle is {{{1}}} longer than each side of the square, than the side of triangle is {{{a+1}}}


the perimeter will be {{{P=3(a+1)}}}


if both gardens have the same perimeter, than we have


{{{4a=3(a+1)}}}

{{{4a=3a+3}}}

{{{4a-3a=3}}}

{{{a=3}}}->the side of square 

then

{{{a+1=3+1=4}}}-> the side of triangle 


so, dimension of square = {{{3m}}}, and dimension of equilateral triangle ={{{4m}}}
