We know perimeter is the amount of units around a figure. If we want to add to a composite figure without increasing the perimeter, we must add to it by using the space on the inside of the figure. For example, if we have a square, we can make it a composite figure by splitting the square with a diagonal line. This adds to the figure without adding to its perimeter.
This is easy trust me everything will be fine first drag it to the bottom right the same way you do it on the Hub and then go 4 units below and you’re all set.
