Question 483228
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(x+x-2)-4}}}
{{{3x=(4x-4)-4}}}
{{{4x-3x=4+4}}}
{{{x=8}}}
 
length of rectangle = 8 inches
width of rectangle = x - 2 = 8 - 2 = 6 inches
