a 24-pack of coke costs $8.49 but a 12-pack of coke cost $5.49. tell what the unit rate is for each pack of coke and which one as the better rate

for 24 pack it's about .35 cents each coke but for the 12 pack its about .46 cents for each coke.. the 24 pack is better

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
