Answer»

Given : Dimension of floor = 18 m by 11 mAndWidth of carpet = 150 cm = 1.5 m ( As we know 1 m = 100 cm )AndCarpet leaving a space of 1.50 m all around , SoDimension of carpet = ( 18 - 1.50 - 1.50 ) m by ( 11 - 1.50 - 1.50 ) m 15 m by 8 mSo,Area of carpet = 15​×8 = 120 m2Let length of carpet required = x, So

width of carpet​×Length of carpet = 120

1.50x= 120

x= 80
