Answer: The perimeter of the rectangle is 31.6 cm.
The perimeter of a rectangle is the sum of the lengths of all four of its sides. In addition, all opposite sides of a rectangle are equal to each other.
Let’s calculate the length. Its value is 8.4 cm more than that of the width:
3.7 + 8.4 = 12.1 cm.
Now, knowing the values of the lengths of all sides of the rectangle, we can start calculating its perimeter:
3.7 + 3.7 + 8.4 + 8.4 = 31.6 cm.
