Question

a marble tile meadures 42 cm by 30 cm find the number of tiles required to cover a wall of 8m by 6.3m​

Answer 1

Answer

Ok I will tell you

Step-by-step explanation:

Length of marble tile = 42 cm

Breadth of marble tile = 30 cm

Area = 42 x 30 = 1260 cm2

or 12.60 m2

Length of wall = 8 m

Breadth of wall = 6.3 m

Area = 8 x 6.3 = 50.4 m2

or 5040 cm2

We will divide it by cm as it will be easy

5040/1260

We will first cut the zero from 1260 and 5040

504/126 = 4 marble tiles
