Answer: -2a+7
Answer:
246
Step-by-step explanation:
next time use a calculator
divide 492 by 2 and you get 246
divide that by 2 and you get 123
and divide that by 3 and you get 41
So to find the perimeter of a square, we must add all of the sides together.
We know that a square's sides are all equal in length and that a square has 4 sides. So that means we need to add 4.7 four times to get the perimeter.
4.7 + 4.7 + 4.7 + 4.7 = 18.8
So the perimeter of the square is 18.8 cm.
