Perimeter = 2 times the width + 2 times the length

= 2(w + 7) + 2w where w = width

2(w + 7) + 2w = 66

4w + 14 = 66

4w = 66-14 = 52

w = 52/4 = 13

length = 13 + 7 = 20

width = 13 and length = 20

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

Step 2: Find Average

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$
