Question

The length of a room is 50 per cent more than its bread
The cost of carpeting the room at the rate of 38.50m2 is
924 and the cost of painting the walls at the rate of 5.50
per m2 is 1,320. Find the dimensions of the room.​

Answer 1

Step-by-step explanation:

Let length (l)=x+1/2x=3/2x

Let breadth (b)=x

Area of floor=924×100/3850

l×b=24

3/2x×x=24

3/2x^2=24

x^2=24×2/3

x^2=4^2

x=4m

Area of 4walls=1320×100/550

2 (l+b) h=240

10×h=240/2

h=12m

l=3/2×4=6m

b=x=4m
