------------------------------------------------------------------------------------
Ratio
------------------------------------------------------------------------------------
Width : Length
    2    :   5 

Let x be the scale factor

Width : Length
    2x    :   5x

------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5

------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x 
Length = 5(5) 
Length = 25

Width = 2x
Width = 2(5)
Width = 10

------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm

Answer: 2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert .

Step-by-step explanation:

Let x be the number of servings of Gerber Mixed Cereal for Baby and y be the number of servings of Gerber Mango Tropical Fruit Dessert .

By considering the given information, we have the following two equations:_

60x+80y=360-----(1)\\\\11x+21y=85------(2)

Divide 20 on both the sides on Equation (1) , we get

3x+4y=18------(3)

Multiplying  11 on both the sides in (3), we get ,

33x+44y=198------(4)

Multiplying 3 on both the sides in (2), we get ,

33x+63y=255------(5)

Now, subtract equation (1) from (2), we get

19y=57\\\\\Rightarrow\ y=\dfrac{57}{19}=3

Substitute Y in (3), we get

3x+4(3)=18\\\\\Rightarrow\ 3x+12=18\\\\\Rightarrow\ 3x=6\\\\\Rightarrow x=2

Hence, you should you 2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert .
