Question

The perimeter of a floor of a room is 17 cm what is the area of four walls of the room if its heights is 4m

Answer 1

A room is generally a 3D figure which is either mostly a cube or a cuboid .

Therefore , let the above mentioned room be a cuboid .

Given ,
Perimeter of base of the room ( rectangle ) = 17 cm

Height of walls = 400 cm or 4m

Therefore area of walls = lateral surface area of cuboid

Lateral surface area of cuboid = (perimeter of base) (height)

= ( 17 cm) (400cm)
=6800 sq cm

Hope this answer is satisfactory
