Area of carpet = lb
=22*15.5
=341m^2
Area of strip left uncovered=2(22*0.75)+2(15.5*0.75)
=33+23.5
=56.5 m^2
=22*15.5
=341m^2
Area of strip left uncovered=2(22*0.75)+2(15.5*0.75)
=33+23.5
=56.5 m^2

The area of carpet would be 287 m² and area of strip would be 54 m²
Area of Carpet would be equal to the area of rectangle with dimensions
(22-0.75 -0.75 =) 20.5 m and ( 15.5-0.75-0.75 ) = 14 m
The area of the carpet would be equal to
14* 20.5 = 287 m²
The area of strip would be equal to area of hall - area of carpet
= 22*15.5 - 14*20.5
= 341 - 287 m²
= 54 m²
