Rectangle ABCD, AB = BC, side AC = 4. find the area of the rectangle.

1. According to the problem statement, sides AB and BC have the same length. This is only possible if the given geometric figure is a square.

2. All sides of this geometric figure have the same length, that is, AB = BC = CD = AD = 4 units.

3. Calculate the area (S) of a given geometric figure:

S = 4 x 4 = 16 units of measure².

Answer: the area of a given geometric figure (square) is 16 units of measurement².
