Answer 1

Answer:

Priyanka need 625 tiles

so (a) is the right answer

Step-by-step explanation:

Priyanka has a square room of side =3.5 m

so the area of Priyanka's room is = $3.5^{2}$ m²

                                                       =12.25m²

the length of the tile is =14cm= 0.14m

therefore the area of the tile is = 0.14² m²

                                                    =0.0196 m²

therefore the no. of tiles needed is = 12.25/0.0196

                                                           = 625

so, Priyanka need 625 tiles .

so (a) is the right answer.
