1. Find the length of the second side of the rectangle, for this we subtract 4 cm from the length of the known side:
12 – 4 = 8 (cm).
2. Find the area of the rectangle by the formula:
S = ab, where S is the area, a and b are the sides of the rectangle.
S = 8 * 12 = 96 (cm2).
Answer: 96 cm2 is the area of a rectangle.
