$1.)$ Convert $50$mile$\frac{s}{?}$ hour to $f\frac{t}{second}.$ Use the conversion factor: $1$ mile $=5,280ft$;$1$ hour $=3,600$ seconds.

$2.)$ For the rectangle below, If side $x=5\mathrm{.}675ft$ and side $y=2\mathrm{.}3ft,$ calculate:

a$.)$ The perimeter of the rectangle.

b$.)$ The area of the rectangle.

Recall, the perimeter is the sum of all the sides, and the area is just the product of side $x$ and $y.$ Be sure to round each answer to the correct number of significant figures.
