Answer:
see the explanation
Step-by-step explanation:
step 1
Find the total yards of the fencing
Divide the total cost by the cost per yard
so
[tex]156/6.50=24\ yd[/tex]
step 2
Draw two possible plans for the garden
case a) A square garden
The perimeter of a square is equal to
[tex]P=4b[/tex]
where
b is the length side of the square
we have
[tex]P=24\ yd[/tex]
substitute
[tex]24=4b[/tex]
[tex]b=6\ yd[/tex]
case b) A rectangular garden
The perimeter of a rectangle is equal to
[tex]P=2(L+W)[/tex]
where
L is the length of the rectangle
W is the width of the rectangle
Assume
[tex]L=8\ yd[/tex]
we have
[tex]P=24\ yd[/tex]
[tex]L=8\ yd[/tex]
substitute
[tex]24=2(8+W)[/tex]
solve for W
[tex]12=8+W[/tex]
[tex]W=12-8=4\ yd[/tex]
