You can
put this solution on YOUR website!Use the following two formulas:
For area use: A = Length times width
For perimeter use: P = 2(length) + 2(width)
L = 12, W = 4
A = 12 times 4
A = 48in^2
The area is 48 squared inches.
==============================
P = 2(12) + 2(4)
P = 24 + 8
P = 32 inches
The perimeter is 32 inches.
The figure given is a rectangle not a square.
