The length of a rectangle is 4n, and twice as long as the width. the perimeter pf the rectangle is twice as long as that of an equalatrial triangle. find the side length of the triangle in terms of n

2n,perimeter of rectangle is 12n ( width is 2n because length is twice of the width)
1/2 of that ( because the perimeter of the rectangle is twice of the equilateral triangle) is 6n. Since its an equilateral triangle, divide 6n by 3 to get 2n
