For convenience, let’s immediately express the sides of the rectangle in centimeters:
30 mm = 3 cm,
50 mm = 5 cm.
The area of the rectangle is found by the formula:
S = ab, where a and b are the sides of the rectangle.
We substitute the values known from the conditions of the problem and find the area:
S = 3 * 5 = 15 cm².
Answer: the area of the rectangle is 15 cm².
