$\"\"$

\

The given values are width(w) $\"\"$ and length(l) $\"\"$ .

\

First find the perimeter:

\

Perimeter(p) = $\"\"$

\

$\"\"$ (Substitute l and w values) \ \

\

$\"\"$ (Commutative property of addition) \ \

\

$\"\"$ (Apply distributive property) \ \

\

$\"\"$ (Add: $\"\"$ ) \ \

\

$\"\"$ (Apply distributive property) \ \

\

$\"\"$ (Multiply: $\"\"$ ) $\"\"$

\

To find the area of rectangle

\

Area (A) = $\"\"$

\

$\"\"$ (Substitute) \ \

\

$\"\"$ (Apply FOIL method) \ \

\

$\"\"$ (Commutative property) \ \

\

$\"\"$ (Multiply: $\"\"$ ) \ \

\

$\"\"$ (Formula: $\"\"$ ) \ \

\

$\"\"$ (Cancel square and root: $\"\"$ )

\

$\"\"$ (Multiply: $\"\"$ ) \ \

\

$\"\"$ (Apply additive inverse property: $\"\"$ ) \ \

\

$\"\"$ (Apply additive identity property: $\"\"$ ) \ \

\

$\"\"$ (Subtract: $\"\"$ ) \ \ $\"\"$

\

The perimeter of rectangle is $\"\"$ and area of rectangle is 12.
