.
Let x = perimeter of smaller square
then from: "12 meters greater than the perimeter of another square"
x+12 = perimeter of larger square
.
length of one side of smaller square = x/4
length of one side of larger square = (x+12)/4
.
(x/4)^2 + 45 = ((x+12)/4)^2
(x^2/16) + 45 = (x^2+24x+144)/16
x^2 + 720 = x^2+24x+144
720 = 24x+144
720 = 24x+144
576 = 24x
24 meters = x (perimeter of smaller square)
.
x+12 = 24+12 = 36 meters (perimeter of larger square)
