re read the first line of your question, is everything correctly typed? just curious if you mean the side of a square is 10 meters longer then the side of a equilateral triangle

A side of a square is 10 meters longer than the side of an equalateral triangle.

ok, 
let x= length of the square and y=length of triangle
so x=y+10
and 4x=3(3y)
4x=9y
rearragne the first equation for y, and sub it in
4x=9(x-10)
4x=9x-90
-5x=-90
x=18 meters
