Answer 1

hye

=======================

A marble tile measures 25 CM by 20 cm

so it is a rectangle has it has different measures

so area of the tile = $l*b$

                               = $25*20$

                               = 500 cm ² 

              


we have to find how many tiles will be needed to cover a Wall of size 4 by 3 metre

area of the qall = l*b

                              = 4*3 = 12 m²

now lets convert 12 m² into cm²
 = 120000 cm²

no. of tiles = 120000/500

                   = 240 tiles

=====================
hope it helps
