Question

Find (x+y)+(x-y) if 5 3 (iii) 0.729 (iv) 12.28 3 2 (ii) x= 4

Answer 1

Answer:

x = 4

Step-by-step explanation:

Perimeter of each tile=12m

Step-by-step explanation:

Given,Length of tile=48m,

Breadth of tile=12m

Number of tiles =64

Area of Hall=Length \times BreadthAreaofHall=Length×Breadth

                            =48m\times 12m48m×12m

 NowArea \ of\ 1\ square\ tile\times Number\ of\ tilesArea of 1 square tile×Number of tiles =Area of Hall

        Area\ of\ 1\ tile\times 64Area of 1 tile×64 =48m\times 12m48m×12m

        Ares of 1 square tiles = \frac{48m\times 12m}{64}6448m×12m

        Area of 1 square tiles=9m

        Area of 1 square tile=3m\times 3m3m×3m

       Side \times SideSide×Side =3m\times 3m3m×3m

      Side= 3m

Now, Perimeter of Square =4\times Side4×Side

                                           =4\times Side4×Side

         Perimeter of Square tile =12m

Hence,Perimeter of each tile=12m.
