Step-by-step explanation:

where,
is the final value
if the initial value
R is the investors rate of return
so,

so the investors rate of return is -11.8%
2(3w-2+w)
=2(4w-2)
=8w-4
the formula for solving perimeters is 2(WL). so L=3w-2, because the question said the length is 2 units shorter than 3 times the width, and the width is w. so the final equation is <span>2(3w-2+w), and then you just have to simplify that </span>
