Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f(x))) = x^2+ x+
posibble answer for x^2 possible answer for x possible answer for
8 -8 4 -20 20 -40 50 -50 25

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 .
