Step-by-step explanation:
GIVEN
A WALL IS COVERED BY 150 TILES
THEN AREA OF TILES
=15*15
=225cm²
since area of wall
=225*160
=36000cm²
then tiles of 10 by 10 needed to cover wall
=area of wall /area of tiles
=36000/10*10
=36000/100
=360 tiles
hence ,tiles of 10 by 10 needed to cover
area of wall=360 tiles
hope this helps you
