Remember, the perimeter is the sum of all sides while the area is the value of the space within the perimeter.

Area = (base) (height)
Perimeter of a rectangle $= 2$ (base) $+ 2$ (height)

$A=79\frac{1}{20}\text{f}t^{2}$
$P=35\frac{9}{10}\text{ft}$

Remember, a square has $4$ sides of equal lengths.

The area of a parallelogram is found by multiplying the base by the height. The perimeter is the sum of the $4$ sides.

The area of a triangle is found by multiplying the base by the height and dividing that product by $2$.

A $= 2653.2$ cm^{$^{2}$}
P $= 278.89$ cm
