#### Answer

$P$ = 48 ft
$A$ = 72 ft$^{2}$

#### Work Step by Step

To find the perimeter add all of the length of sides together.
$P$ = 4 ft + 12 ft + 12 ft + 3 ft + 8 ft + 9 ft
$P$ = 48 ft
To find the area we can break the shape into two rectangles. The first measuring 4 ft x 12 ft and the second measuring 3 ft x 8 ft. Find the area of each and then add the results together to determine the total area.
$A$$_{1}$ = 4ft * 12 ft
$A$$_{1}$ = 48 ft$^{2}$
$A$$_{2}$ = 3 ft * 18 ft
$A$$_{2}$ = 24 ft$^{2}$
$A$ = A$_{1}$ + A$_{2}$
$A$ = 48 ft$^{2}$ + 24 ft$^{2}$
$A$ = 72 ft$^{2}$
