The side lengths of the rectangle are 6 cm and 8 cm. Find the perimeter of the rectangle whose side lengths are twice the lengths of the sides of this rectangle.
First, we find the lengths of the sides of the rectangle, if it is known that they are 2 times more than 6 cm and 8 cm:
6 * 2 = 12.
8 * 2 = 16.
To find the perimeter of a rectangle, you need to multiply the sum of its two sides by 2.
We get:
2 * (12 + 16) = 2 * 28 = 56 cm (rectangle perimeter).
Answer: 56 cm.
