Question

Can you please help me ? Just need the answer pls

Answer 1

Area of extension is, 32.625 sq. metre

no. of tiles needed = 522

no. of complete package of tiles needed = 20

Explanation:

Area of the patio

=
`6.25^(2)` sq. metre

= 39.0625 sq. metre

Area of the patio ( with extension)

=
`(6.25 + 2* 1.5) * (6.25 + 1.5)` sq. metre

= 71.6875 sq. metre

So,

area of the extension ,

= (71.6875 - 39.0625) sq. metre

= 32.625 sq. metre

Area of a tile

=
`0.25 \ times \0.25` sq. metre

= 0. 0625 sq. metre

So, number of tiles needed,

=
`(32.625)/(0.0625)`

=522

no of complete package of tiles needed,

`[(522)/(25)]`

= 20
