Question

the area four walls in a room is 120 m. the length of room is twice then breadth. if the hight isthe room 4 m. find the area of floor

Answer 1

Here is the answer for your question

Let breadth of the room = b m
Length= 2b m
Height= h= 4m
1) area of the four walls of the room = 2(length+breadth)*h
2(2b+b)*4=120m^2
8*3b=120
b=120/(8*3)
b=5m
Therefore
Breadth=b=5m
Length=2b=2*5=10m
2)area of the floor= length*breadth
=10m*5m
=50squremeter
