Question

A marble tile measure 30 into 25 cm find the number of such that required to cover a Wall of size 4 *3

Answer 1

Answer:

160 tiles of 30cm×25cm will be required to cover the wall.

Step-by-step explanation:

Given, the dimension of 1 tile = 30cm * 25 cm

Therefore, the area of 1 tile = 750cm²

Dimensions of the wall = 4m * 3m

                                      = 400cm * 300cm          (as 1m = 100cm)

We have converted the dimensions in cm as the measurement of the tile was given in cm.

Therefore, the area of the wall = 120000cm²  

We know that the number of tiles = $\frac{area of wall}{area of 1 tile}$

                                                        = $\frac{120000}{750}$

                                                        = 160          

Therefore, 160 tiles of 30cm×25cm will be required to cover the wall.
