A regular chicken pen is 4 times as long as it is wide. If the area of the pen needs to be 144 square feet, hot much fencing is needed to enclose the garden (perimeter)? (The long side of the rectangle is 4w and the short side is w). Step by step!

60

Step-by-step explanation:

Length=4w

Width=w

Area=length×width

144= 4w × w

4w²=144( Divide both sides by 4)

w²=36

w²-36=0 (Factorise the Quadratic Equation)

(w+6)(w-6)=0

(w+6)=0 or (w-6)=0

w= -6 or w=6

Since length can't be a negative value,

w=6

4w=6×4=24

Perimeter= 6+6+24+24=60

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
