Answer 2

Answer:

${\huge{\underline{\underline{\sf{\blue{Question :-}}}}}}$

A floor is 5 metre long and 4m wide. A square carpet of sides 3 metre is laid on the floor . Find the area of the floor that is not carpeted.

${\huge{\underline{\underline{\sf{\blue{Solution :-}}}}}}$

Hence,

Area of the floor = length × breadth (formula)

$= 5 m × 4 m = 2 m ^{2}$

Area of the square carpet = (side) × (side)

$= 3m \: \times \: 3m \: = 9m ^{2}$

Area of the floor , that is , not carpeted

= Area of the floor - Area of the square carpet

$= 20 m ^{2} - 9m ^{2} = 11m ^{2}$
