Question

Find the area of four walls of a room 8 m long , 6 mwide and 5 m height

Answer 1

Answer:

Step-by-step explanation: area = length ×breadth ×height

So,

8×6×5=240

Answer 2

Area of four walls = 2*(length+breadth)*height

                            = 2*(8+6)*5 m^2

                            = 10*14 m^2

                            = 140 m^2
