Question

.The cost of colouring the walls of a room 8m long at ₹22/sq.m is ₹2640 and the cost of tiling the floor at ₹1400/sq.m is ₹78400.Find the height.​

Answer 1

Answer:

cost of tiling the floor is ₹ 78400

area of the floor is 78400/1400 sq m

=56 sq m

length=8 m

so breadth=56/8 m=7 m

area of 4 walls =2640/22 sq m

=120 sq m

ih h is the height then area of 4 walls

2(8+7).h=120

=> 30h=120

=> h=120/30

=> h=4

so, height is 4 m

Answer 2

Answer:

I am only giving you the solution ok pls mark as brainlist

Step-by-step explanation:

Cost of flooring per square meter = Rs.8.50

⇒ Total cost of flooring of room = Rs.510

∴ Area of the room =

8.50

510

=60m

2

⇒ Area of the room = l×b

⇒ 60=8×b

∴ b=

8

60

=7.5m.

∴ Breadth of the rioom is 7.5m.
