To complete this task, we first need to find the value of the length of the rectangle, knowing that it is 2 times the width, equal to 4 dm. To do this, we perform multiplication.
4 * 2 = 8 dm.
We calculate what the area is equal to, knowing that to find it, you need to find the product of the length and width.
S = 8 * 4 = 32 m².
We calculate the value of the perimeter, knowing that it is equal to twice the sum of the length and width.
P = 2 * (8 + 4) = 2 * 12 = 24 cm.
Answer: 24 cm, 32 m².
