Answer:
The length of the room floor (l) = 15m
The breadth of the room floor (b) = 9.5m
area of the room floor = lb = (15)(9.5)m² = 142.5 m²
Length of the square carpet (a) = 11m
Area of the square carpet = a² = 11²m² = 121m²
The area of the floor left uncarpeted = area of floor - area of the carpet
= 142.5m² - 121m² = 21.5m²
