Question

calculate the area and perimeter.
12 in.
8 in.
perimeter:
area:

Explanation:

Step1: Calculate perimeter of rectangle

Perimeter formula: $P = 2(l + w)$
Substitute $l=12$, $w=8$:
$P = 2(12 + 8) = 2\times20 = 40$

Step2: Calculate area of rectangle

Area formula: $A = l\times w$
Substitute $l=12$, $w=8$:
$A = 12\times8 = 96$

Answer:

Perimeter: $40$ in.
Area: $96$ in.$^2$
