Answer 1

i hope it's help u....xd

Answer 2

Answer:

Let Length=l,breath=b,height=h

Area of four walls = 2h(l+b) = 108m  

2

 

h:l=2:5,h:b=4:5 (Given)

∴h:l:b=4:10:5

Let h=4x,l=10x,b=5x

Now, the area of four walls, 2×4x(15x)=108

x  

2

=  

120

108

​  

 

Then the area of the floor is l×b=10x×5x=50x  

2

 

=50×  

120

108

​  

=45m
