December 29, 2020 | education

| If the length of the rectangle is 18 cm, and the width is 3 times less, then we find its width:

18/3 = 6.

The perimeter of a rectangle is equal to the sum of the milestones of its sides, taking into account that the opposite sides are equal:

18 * 2 + 6 * 2 = 36 + 12 = 48.

The area of a rectangle is equal to the product of its length and width:

18 * 6 = 108.

Answer: the perimeter of the rectangle is 48 cm; the area of the rectangle is 108 cm2.
