Answer:

i.
P=4y+6

ii.
$P=30\:ft$

Explanation:

The given rectangular garden has width,
w=3ft and length,
$l=2y\:ft$ .

The perimeter of a rectangle is calculated using the formula;

P=2l+2w

We substitute the given dimensions into the formula to get;

P=2(2y)+2(3)

$\Rightarrow P=4y+6$

We substitute;

y=6 to obtain;

$\Rightarrow P=4(6)+6$

Simplify;

$\Rightarrow P=24+6$

$\Rightarrow P=30ft$
