The width of the rectangle is 8cm, which is half of its length. find the perimeter of the rectangle.

1. First, let’s calculate what the length of the rectangle is, if it is known from the condition that the width is half the length and is equal to 8 cm.Then we will double the width of the rectangle and get its length:
8 cm * 2 = 16 cm.
2. Now, knowing the length of the width of the figure, we can calculate the perimeter of the rectangle. To do this, the doubled length value must be added to the doubled width value, we get the following expression:
2 * 8 cm + 2 * 16 cm = 16 + 32 = 48 cm.
Answer: in the course of the calculations done, we obtained a perimeter value equal to 48 centimeters.
