The perimeter of a rectangle is the sum of all the sides of the rectangle.
P = 2 * (a + b);
P = 2 * (a + 1/3 * a);
P = 2 * (a + 1/3 * a);
P = 8/3 * a = 32;
a = 12.
One side of the rectangle is 12 cm, and the other is 4 cm.
S = a * b;
S = 12 * 4 = 48 cm2.
Answer: the area of the rectangle is 48 cm2.
