Answer:
1 cm
Step-by-step explanation:
Since the perimeter is 4 cm and all the sides of the square have the same length, each side must be 1 cm long.
The area of that square is 1 cm x 1 cm, which is 1 cm2.
We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.

Answer:
Minutes to make one balloon sculpture = 5 minutes
Balloons are used for one balloon sculpture= 8 balloons
Tomas use balloons = 1.6 per minute
Step-by-step explanation:
a).
180 minutes = 36 sculpture
![\frac{180 }{36 } = 5](https://tex.z-dn.net/?f=%5Cfrac%7B180%20%7D%7B36%20%7D%20%3D%205)
5 minutes to make a sculpture
b).
288 balloons = 36 sculpture
![\frac{288 }{36 } = 8](https://tex.z-dn.net/?f=%5Cfrac%7B288%20%7D%7B36%20%7D%20%3D%208)
8 Balloons to make a sculpture
c).
288 Balloons = 180 minutes
![\frac{288}{180} = 1.6](https://tex.z-dn.net/?f=%5Cfrac%7B288%7D%7B180%7D%20%3D%201.6%20)
1.6 Balloons per minute
