Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:

A binomial distribution has the following properties;
1. There is a fixed number of trials.
2. Each trial is independent of the others.
3.Each trial has a constant probability of success.
4. There are only two possible outcomes, 'success' and 'failure'.
Statements B and D meet the requirements for the variable X to have a binomial distribution.
4 times 7 = 28
3 times 7 = 21
It will take him 21 days to make 28 bird houses.
