1. ## Garden root

A rectangular garden has length $3 \sqrt 6$ metres and area $(9\sqrt2 - 6\sqrt3)$ square metres.

a) Write and simplify an expression for the width of the garden.
b) Determine the perimeter of the garden to the nearest tenth of a meter.

I'm sooo confused

ok, so for a rectangle, area = length times width. so, if we let the width be
$x$, we must have that

$3 \sqrt{6}x = 9 \sqrt{2} - 6 \sqrt{3}$

now solve for $x$ and simplify the answer

b) Determine the perimeter of the garden to the nearest tenth of a meter.
remember, the perimeter is the distance around the figure, that is, the length of all the sides. the perimeter for a rectangle with width $x$ and length $y$ is given by:

$P = 2x + 2y$
