The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.
The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:
A = s²
36 sq. units = s²
√(36 sq. units) = √s²
6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)
Therefore, ...
P = 4s
P = 4(6 units)
P = 24 units is the perimeter of a square whose area is 36 square units
Answer:
2 lbs. for $4.50
Step-by-step explanation:
Do a ratio
2 : 4.50
You want to see how much it cost per pound, so divide them by 2
2 ÷ 2 : 4.50 ÷ 2
1 : 2.25
So per pound, the hamburger will cost $ 2.25
________________________________________________________
3 : 6.90
You want to see how much it cost per pound, so all you need to do is divide them by 3
3 ÷ 3 : 6.90 ÷ 3
1 : 2.3
So for the first one, it cost 2.25 per pound, and for the second one, it cost 2.3 per pound....the one that is better will be 2.25 because it cost 5 cents less than the second one
Hope this helped!

Don’t know but you do have to subtract
B. 180cm3
You have to find length, width, and height of both objects.
For the first one multiply:
3 x 8 x 5 = 120
Then multiply:
2 x 5 x 6 = 60
Add them together:
120 + 60 = 180cm3
