Find the dimensions of the rectangle.

Step-by-step explanation:

let width=w

length=3w-1

area=w(3w-1)=310

3w²-w-310=0

3w²-31w+30w-310=0

w(3w-31)+10(3w-31)=0

(3w-31)(w+10)=0

w=-10(rejected),31/3

length=31/3×3-1=31-1=30

length=30 ft

width=31/3 ft=10 1/3 ft

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time
