The perimeter of a rectangle is equal to the sum of all its sides. Let us express the unknown side with the letter x and write the equation:

x + x + 6 + 6 = 32 cm;

2x + 12 = 32;

2x = 32 – 12;

2x = 20;

x = 20/2;

x = 10 cm;

The area of a rectangle is equal to the product of its sides:

S = 6 * 10 = 60 cm².
