Question

the floor of a room is in the shape of a square of side 4.8 M the floor is to be covered with square tiles of parameter 1.2 M find the cost of covering the floor if each tile cost rupees 27

Answer 1

Perimeter=4.8×4=19.2
Perimeter of tile =1.2

19.2/1.2=16

Cost=16×27=Rs.432

Answer 2

area of square = 4.8*4.8=23.04
perimeter of tiles = 1.2
4* side= 1.2
side of tiles = 0.3
area of tiles = 0.3*0.3=0.09
23.04/0.09=256
cost= 27*256= 6912
