1.	1) The length and breadth of the floor of a hall are 420 cm and 260cm. howmany square tiles each of side 20cm are needed to cover the floor?
Answer» Answer: STEP1:- LENGTH = 420 cm and breadth= 260 cm step2:-area of rectangle :- length × breadth step3:-area of rectangle = (420 × 260) cm² =109200 cm² step4:- side of square tile = 20 cm step5 :- area of square = (side)² =(20)²=400cm² step6:- number of TILES required = 109200/400 =273 273 number of tiles are required for covering the floor.

Answer:

STEP1:- LENGTH = 420 cm and breadth= 260 cm

step2:-area of rectangle :- length × breadth

step3:-area of rectangle = (420 × 260) cm²

=109200 cm²

step4:- side of square tile = 20 cm

step5 :- area of square = (side)²

=(20)²=400cm²

step6:- number of TILES required = 109200/400

=273

273 number of tiles are required for covering the floor.
