Answer:
3.6m
Step-by-step explanation:
Find the area of the square tile i.e.
(30*30)cm^2
900cm^2
number of pieces =144
area covered by whole
=(900*144)cm^2
=129600cm^2
we know that area of square =side*side
side = √area of square
side = (√129600)cm
side =360 cm
to convert in metre i.e.
360/100
3.6 m
