Noah has 50 feet of fencing to completely enclose a rectangular garden in the backyard. Find the length and width of a rectangle that would produce the largest possible area

Length = 12.5 feet

Width = 12.5 feet

Step-by-step explanation:

We can set two equations to solve this problem.

First equation:

The perimeter of a rectangle is 2*L + 2*W, where L is the lenght and W is the width, and Noah has 50 feet of fencing to use, so:

2*L + 2*W = 50

Second equation:

The area of the rectangle (A) is calculated mutiplying the lenght by the width:

A = L * W

Dividing the first equation by 2 and isolating L, we have:

L + W = 25 -> L = 25 - W

Using this equation in the second one, we have:

A = (25 - W)*W = 25W - W^2

The formula to calculate the point that gives the maximum value is:

x = –b/2a

So, the value of W that gives the maximum area will be:

W = -25/2*(-1) = -25/(-2) = 12.5 feet

Using this value in the first equation W + L = 25, we have:

12.5 + L = 25

L = 12.5 feet

So, the length and width that produce the largest possible area are 12.5 feet and 12.5 feet.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
