1) The area of the rectangle can be calculated using the formula:
S = a * b, where a is the length of the rectangle (a = 12 cm), b is the width of the rectangle (b = a – 4 = 12 – 4 = 8 cm).
S = a * b = 12 * 8 = 96 cm2.
2) The perimeter of the rectangle can be calculated using the formula:
P = 2 * (a + b) = 2 * (12 + 8) = 2 * 20 = 40 cm.
Answer: The area of the rectangle is 96 cm2, the perimeter of the rectangle is 40 cm.
