. What is the perimeter of this square?
12 in.
. What is the area of this square?

P = 48 in.  A = 144 in.^2

Step-by-step explanation:

All 4 of a squares sides are equal length.

To find the perimeter, you add up all the sides.

Because you know one side is 12 in, just add 12 three more times.

P = Perimeter

P = 12 + 12 + 12 + 12 = 48 in.

To find the area, you need to multiply base and the height.

You already know the base and the height are the same, 12.

A = bh

A = 12 × 12 = 144 in.^2

(Keep in mind that when doing area, the unit is squared. Perimeter is not.)
