Answer:
3 feet
Step-by-step explanation:
Squares have an equal side length. So on all sides, your square would have 0.75. And if we multiplied 0.75 by 4, because of its 4 sides, the perimeter would be 3.
Now, I do understand that you have to add the sides, but adding 0.75 + 0.75 + 0.75 + 0.75, 4 times, is practically the same things as multiplying it by 4 times!
I hope this helped!
