In a rectangle, one side is 16 and the other is 3 cm, find the area of the rectangle.

By the condition of the problem, a rectangle is given.
Let its sides be sides a and b.
Find the area of this rectangle.
First, we write down the formula by which we will find the required area.
S = ab.
By condition, it is known that a = 16 cm and b = 3 cm.
Substitute the specified data a and b into the formula.
S = ab.
S = 16 × 3.
S = 48 (cm²).
Answer: S = 48 cm².
