Find the area and perimeter of a rectangle with sides of 6 cm and 5 cm.

1) We calculate the area of a given rectangle (S), knowing that it is determined by the formula:
S = a * b, where a is the length of the rectangle, b is the width of the rectangle.
S = 6 * 5 = 30 cm2.
2) Calculate the perimeter of a given rectangle (P), knowing that it is equal to the sum of the lengths of all its sides:
P = a + b + a + b = 2a + 2b.
P = 2 * 6 + 2 * 5 = 12 + 10 = 22 cm.
Answer: the area is 30 cm2, the perimeter is 22 cm.
