Martin and Edward are neighbors. Martin has a rectangular backyard whose length is 12 feet and whose width is 6 feet. Edward's backyard is a square that shares a side of Martin's backyard (the width). The men decide to line each side of both yards with hedges. At the end of the gardening project, how many feet of hedges have Martin and Edward laid?

They have both laid a total of 54 feet of hedges

Step-by-step explanation:

Here, we have a square bordered by a rectangle

The dimensions of the rectangle is 12 ft by 6 ft

The dimensions of the square is same all through and since it shares the width with the rectangle;

The dimensions of the square will be 6 ft by 6 ft

So since they decided to lay each side with edges,

The total hedges laid will be;

6 + 6 + 6 + 6 + 12 + 12 + 6

5(6) + 2(12)

= 30 + 24 = 54 ft

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
