Vivian is at a fair in coachella valley, california. much of the valley lies below sea level. vivian has brought along an altimeter to measure her elevation at different places in the valley. vivian's first ride was on the ferris wheel. when she sat on the wheel at its lowest point, her altimeter read -9.6 feet. when she reached the top of the wheel, her altimeter read 12.3 feet.

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 .
