rectangular tile each of size 70 cm by 30 cm must be laid horizontally on a rectangular floor of size 110 cm by 130 cm , such that the tiles do not overlap and they are placed with edges jutting against each other on all edges . a tile can be placed in any orientation so long as its edges are parallel to the edges of floor . no tile should overshoot any edge of the floor . the maximum number of tiles that can be accommodated on the floor is :
"area of tile = 70 * 30 = 2100 area of floor = 130 * 110 = 14300 no of tiles = 14300 / 2100 = 6.8 so , the no of tile = 6 answer : b"
divide(multiply(110, 130), multiply(70, 30))
