The volume of a rectangular prism can be found from the formula V=B•h
The base is the triangle
The area of the triangle can found using A=b•1/2h
13•1/2(8)=52
V=52 x h
52•9=468
468in^2
(6) / (4.5) = 4 / 3 = 1.333...
The level increased by 33-1/3 % .
The old level was 75% of the new level.
The amount of water in the pool also had to
increase 33-1/3 % . If you didn't have that
much water to put in the pool, you couldn't
change the surface level from 4.5ft to 6ft .
Answer:
Part a) The inequality that models this problem is 
Part b) The greatest possible value for the width is 10.6 centimeters
Step-by-step explanation:
Part a) Which inequality models this problem?
Let
l ----> the length of the rectangle in cm
w ---> the width of the rectangle in cm
we know that
The perimeter of the rectangle is equal to

Remember that
The term "at most" means "less than or equal to"
so
----> inequality A
---> equation B
substitute equation B in the inequality A
---> inequality that model the problem
Part b) what is the greatest possible value for the width?
solve for w


Divide by 10 both sides

therefore
The greatest possible value for the width is 10.6 centimeters
