brainy The first time Jane went to the fitness center she exercised for 20mins. she adds 10 mins to her exercise program every other day after that. how many days will it take jane to build her exercise program every other day after that. how may days will it take Jane to build her exercise program up to an hour in length? how do i setup this problem?

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 .

sorry i do not     know the answer
