The width is 
Step-by-step explanation:
we know that
The area of rectangle is equal to

we have

so
-----> equation A
------> equation B
substitute equation B in equation A and solve for L


using a graphing tool------> solve the quadratic equation
The solution is 
see the attached figure
<em>Find the value of W</em>
Answer:
C. Approximately normal
Step-by-step explanation:
We know that when we have, np≥10, and n(1−p)≥10, and both of these are true, where n is the sample size, and p is the sample of proportions, the sampling proportions of sample distributions, will be normal in shape.
Expected successes : np=125(0.88)=110≥10
Expected failures : n(1−p)=125(1−0.88)=15≥10
3÷3=1
3÷12=4 so the answer is 1/4
