The cost of carpeting a square room at Rs. 36 per m2 is Rs. 1764. If the cost of papering its walls at Rs. 16 per m2 is Rs. 2240, find the height of the room.​

for the points

step-by-step explanation:

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

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 .
