Question

The area of the four walls of a room is 80cm square and height is 4cm then the perimeter of the floor is

Answer 1

Answer:

let the dimensions of the room are

Length =l m

breadth =b m

Height = h=4m

perimeter = 2(l+b)

area of the four walls = 80m^2

2(l+b)*h=80

2(l+b)= 80/h

therefore

perimeter = 80/4

=20m
