Answer:

rectangle A:

LENGTH:9

WÄ°DTH:6

rectangle B:

LENGTH:9

WÄ°DTH:3

Step-by-step explanation:

if you want to find the length of a square you should know that in a square all 4 sides lengths are the same so the are is give as 36 to find 1 side of the length we have to divide 36 with 4(because there are 4 sides)

which means the lengths of each side is 9.

it is the same as in rectangle a and b length hasn't changed only the width has changed.

we can also find the width with the information given us about its ratio.  

it says that The ratio of area A to area B is 2:1

the length is 9:

we can make it simple like this lets say 2x and 1x has to give us 9

so we can say 3x=9,x=3

to find the width we can say that 2x width is for rectangle A and 1 x is rectangle B. so x was 3:

2x=6

1x=3

these are the widths of rectangle A and B
