Find the perimeter of a 1 m2 square, expressed in centimeters. find the perimeter of a shape made up of three such squares.

The area of the square is: S = a * b = a ^ 2. Substituting our value for the area, we get: 1 cm square = a ^ 2, a = 1 m. The perimeter of a square is equal to the sum of all its sides. Since all sides of the square are equal, then P = 4 * a. Substituting the known value of the side, we find the perimeter: P = 4 * 1 m = 4 m. Let us express the value of the perimeter in dm. Since 1 m = 10 dm, then 4 m = 4 * 10 dm = 40 dm – the perimeter of the square. Find the perimeter of a figure made up of three such squares. This figure will have two sides of 2 m and 4 sides of 1 m, so the perimeter of the figure is: R f = 2 * 2 + 4 * 1 = 4 + 4 = 8 m = 80 dm.
