Answer 1

Answer:

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) = 14m

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

= 341-287m2

= 54m2
