Question

The perimeter of a floor of a room is 24m and it's height is 3 m. Find the area of four walls of the room

Answer 1

Hiiii friend,


Perimeter of room = 24 m


2(Length + Breadth) = 24


Length + Breadth = 24/2


Length + Breadth = 12 m

And,


Height of room = 3 m


Therefore,


Area of four walls = 2(L + B) × H


Area of four wall = 2(12) × 3 = 24 × 3 = 72 m



HOPE IT WILL HELP YOU...... :-)

Answer 2

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

Here,


Perimeter = 2(length+Breadth)

=> 24 = 2(length+breadth) -----1equation

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


Putting the value of 2(length +Breadth) from 1equation,



Area of four walls = 24 × 3


Area of four walls = 72 m²



I hope this will help you
