Solution
Length (l) = 5 m
Breadth (b) = 4 m
Area of floor = l × b = 5 × 4 = 20 m2
Area covered by the carpet = (Side)2 = (3)2 = 9 m2
Area not covered by the carpet = 20 − 9 = 11 m2
Length (l) = 5 m
Breadth (b) = 4 m
Area of floor = l × b = 5 × 4 = 20 m2
Area covered by the carpet = (Side)2 = (3)2 = 9 m2
Area not covered by the carpet = 20 − 9 = 11 m2
