To solve for area:
A=lw (Area equals length times width)
The length and width are both 12. Substitute 12 for l and w.
A=12x12
Multiply.
A=144
The room has an area of 144 units.
To solve for perimeter:
P=2l+2w (Perimeter equals two time the length plus two times the width).
Substitute 12 for l and w.
P=(2x12)+(2x12)
Simplify.
P=24+24
P=48
The room has a perimeter of 48 units.
