Answer: 72Cm
Step-by-step explanation:
The perimeter is 4 times 1 side
currently, it is 9 times 4 or 36
increased by 3
I think y mean times 3
so 9*3=27
new perimeter is 27*4=108
how much larger is it?
108-36=72
it is 72cm larger
it is the first answer
(it isn't cm² because that is for area and we are calculating perimeter)
