The perimeter of a shape is the sum of the visible lengths of the shape. Adam does not have enough ribbon to decorate the top of the box.
I've added the gift box, as an attachment.
From the attached image, we have:
Next, we calculate the length and the width of the box using:
The top and bottom edges are square. This means that:
So, we have:
Substitute known values
Divide both sides by 8
Take square roots of both sides
So, we have:
Calculate perimeter (P) of the top edge of the box
This means that Adam needs 24.4 cm of gold ribbon to wrap the top edge
By comparison:
or
24.4 cm is greater than the length of Adam's gold ribbon (24.25).
Hence, we can conclude that he does not have enough ribbon to decorate the top of the box.
