Answer 1

Answer : 

Given : Dimension of floor  =  18 m by 11 m 
And 
Width of carpet =  150 cm  =  1.5 m ( As we know 1 m  =  100 cm )
And 
Carpet leaving a space of 1.50 m all around , So 
Dimension of carpet  = ( 18 - 1.50 - 1.50 ) m  by ( 11 - 1.50 - 1.50 ) m   15 m by 8 m 
So,
Area of carpet  =  15 ​× 8  = 120 m2 
Let length of carpet required  =  x  , So

width of carpet ​× Length of carpet  = 120 

1.50x  = 120 

x  = 80
