Question

how many rhombus shaped tiles will be needed for a hall 12 m long and 8 m wide. if the diagonals lengths if the tile are 6cm and 8cm respectively . ​

Answer 1

Answer:

area of the hall: lb

                           12m*8m=1200cm*800cm

                            960000cm^2

Step-by-step explanation:

let CA = 6cm; AI =3cm

   BD = 8cm: BI = 4 cm

   AB=√(BI)^2+(AI)^2

          √(16+9)

           √25cm^2

            5cm

area of an rhombus tile : (s)^2

                                       25cm^2

no. of tiles needed= 960000cm^2/25cm^2

                                 =38400 tiles
