Question

The cost of papering the walls of a room 12 m long at the rate of t 13.50 per square metre is 3402 and the cost of matting the floor at 9.50 per square metre is t 1026. Find the height of the room​

Answer 1

Answer:

20.86 m

Step-by-step explanation:

Cost of papering wall = ₹3402

So,

₹3402 = L × H × ₹13.50 /m²

₹3402 = 12 m × H × ₹13.59 /m²

H = (₹3402) / (12 m × ₹13.59 /m²)

H = 20.86 m
