5x^2+x-x^2+4x

a- 4x^2+5x
b- 5x^2+5x
c- 4x^2+3x
d- 6x^2+5x

triangle and cube

step-by-step explanation:

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

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 .

well, if it's triangular garden, the triangle could represent the garden.
