The equation for the perimeter of a square is P=4s (s=the length of each side) So we can plug in the perimeter and solve for the side 48=4s s=12 (divide both sides by 4)
The equation for the area of a square is A=s^2 or A=s*s We can plug in the value for each side to find the area A=12*12 A=144 units
