    Bailey I guess the sides of the rectangle are 2x and 3x + 2 ?

    If so 170 = (2x)(3x + 2) Which gives 170 = 6x^2 + 4x Convert to a quadratic equation 6x^2 + 4x - 170 = 0 Factorise which will give solutions of x as 5 or -5.6666 disregard the negative solution as you are looking at a measured length Answer x = 5

    ...so if x = 5 the perimeter is 2(2*5) + 2([3*5] + 2) Hence perimeter is 20 + 34 = 54 feet
