1. Find the width of the rectangle if it is known that it is 4 times less than the length:
36 mm / 4 = 9 mm.
2. To find the area of a rectangle, use the formula S = a * b, where S is the area of the rectangle, a and b are the length and width of the rectangle:
S = 9 * 36 = 324 mm2.
Answer: the area of the rectangle is 324 mm2.
