Question

the length , breadth and height of a room are 10m,6m and 2.5 m respectively. find the area of the four walls of the room.

Answer 1

area of room =2h(l+b)
=2x2.5(10+16)
=5x26
=130

Answer 2

Answer: 80

Step-by-step explanation:

Given:- Length - 10m

            Breadth - 6m

             Height - 2.5m

Find - The area of the four walls of the room = ?

Formula of Curved Surface Area:- 2*h(l + b) units

So The area of the four walls of the room = 2*h(l + b)m

                                                                      =2*2.5(10 + 6)m

                                                                       =(5*16)m

   The area of the four walls of the room   = 80m.
