Answer 1

Answer:

$\large\boxed{P=(16+36x)\ ft}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=bh$

b - base

h - height

We have A = 144x ft² and h = 8. Substitute and solve for b:

$144x=8b$              divide both sides by 8

$b=18x\ ft$

The formula of a perimeter of a rectangle:

$P=2b+2h$

Substitute:

$P=2(18x)+2(8)=36x+16$
