You can put this solution on YOUR website!
let x = length of the sides of the equilateral triangle
so, the length of rectangle is x also and the width is x - 2
Perimeter of the triangle = Perimeter of the rectangle - 4
3x=2%28x%2Bx-2%29-4
3x=%284x-4%29-4
4x-3x=4%2B4
x=8

length of rectangle = 8 inches
width of rectangle = x - 2 = 8 - 2 = 6 inches
