Question

The length of a room is two times its
height while its breadth is 1 by 1/2 times its
height. The cost of painting the walls at
the rate of Rs. 16 per m² is Rs. 1792.
What is the cost of tiling the floor at Rs.
132.5 per m??​

Answer 1

Answer:

Rs.612

Step-by-step explanation:

Let height be x

Length=2x

Breadth =1 1x/2=3x/2

Area of 4 walls of room=179.20÷1.60=112m^2

2 (l+b)×h=112

2 (2x+3x/2)×x=112

2×7x^2/2=112

x^2=16

x=4

So height=4m

Length=8m

Breadth=6m

For tiling the floor we will find the area

Area=l×b=8×6=48m^2

Cost of tiling the floor =48×12.75=Rs.612

Required answer is Rs.612
