The width of the rectangle is 4 dm, which is half the length. Find the area and perimeter of the shape.

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.
