a. Ratio of blue: green
Length blue: length green
3:6 or 1:2
Width blue :width green
2:4 or 1:2
Perimeter blue: perimeter green
2+2+3+3=10: 4+4+6+6= 20 or 1 :2
Area blue: Area green
2•3=6 : 4•6= 24 or 1:4
b. The lenght, with and perimeter of the big green rectangle are double the size of the small blue rectangle.
The area of the big green rectangle is 4 times greater than the area of the small blue rectangle. So if the lenghts of a rectangle are doubled the perimeter is doubled and the area is 4 times biger than the area of the doubeled rectangle.

Step-by-step explanation:
1.) 90 Km/h. Example: What is the speed of a cheetah that travels 112.0 meters in 4.0 seconds? ... Speed of the cheetah in miles per hour 28m 1 mile 3600 s 63 miles
2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.
12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.
1.2 = k
Next write the equation using this k and the h & n.
h = 1.2*n
Now we want to find the height if we have 24 books so plug 24 in for n.
h = 1.2 * 24
h = 28.8 inches
3.) 10/3
