Answer:
the room square side is 4.8m
Area of the room is= 4.8=²23.04²m
perimeter of square tiles=4a =1.2
a=1.2/4
or a=o.3m
area of the square tiles =0.3²=0.09m²
numbers of the tiles are rcover floor of the room
23.0.4/0.09=256
each tiles cost Rs 27
the total cost=256*27=6912
the th coalst cover by the th floor is Rs .6912
H^2=x^2+y^2
y^2=h^2-x^2
y^2=40^2-24^2
y^2=1024
y=√1024
y=32 ft
$ 295 because you can multiple 15×19.7 is =295.5
23z pretty sure sorry if it’s wrong
