Question

find the answer with step

Answer 1

Answer:

no. of tiles=18000 cost= rs. 225000

Step-by-step explanation:

given side of square = 9 m

that is equal to 900 cm

so the area of floor = (900 x 900) cm

                                = 810000 sq.cm

ar. of 1 tile = (15 x 3) cm

                  =45 sq. cm

no. of tiles =ar. of floor / ar. of tile

= 810000/45

=18000

cost =12.5 x 18000

rs.225000
