Question

solve it give me full solution​

Answer 1

SIDE OF A SQUARE TILE=10 cm

THEREFORE,

AREA OF TILE=(10 × 10)cm²

=100 cm²

LENGTH OF WALL=200 cm

BREADTH OR HEIGHT OF WALL=250 cm

THEREFORE,

AREA OF WALL=(200 × 250)cm²

=50,000 cm²

NOW,

NUMBER OF TILES NEEDED=(50000/100)TILES

=500 TILES.
