A farmer plans to enclose two adjacent rectangular pens against a barn wall (see figure).
Licemer1 [7]

Answer: Let's assume that the pig pens need to be fenced in the way shown in the diagram above.

Then, the perimeter is given by

4

x

+

3

y

=

160

.

The area of a rectangle is given by

A

=

L

×

W

, however here we have two rectangles put together, so the total area will be given by

A

=

W

.

A

=

4

y

)

Now, let's differentiate this function, with respect to y, to find any critical points on the graph.

20

x

=

Hence, the dimensions that will give the maximum area are

feet.

A graphical check of the initial function shows that the vertex is at

, which represents one of the dimensions that will give the maximum area and the maximum area, respectively.

Hopefully this helps!

Please help me with this math problem!! :)
GarryVolchara [31]

Step-by-step explanation:

the following things are clear : opposite sides are of equal length, the sum of all angles in a square, rectangle or general parallelogram is 360 degrees, and opposite angles are equal.

so,

y² + 7 = 32

y² = 25

y = 5

2y² = k

2×5² = k

50 = k

the opposite angle of 150 is also 150 degrees.

the opposite angle of x is also x.

so, we have as sum of angles

360 = 150 + 150 + x + x = 300 + 2x

60 = 2x

x = 30 degrees
