Step-by-step explanation:
A wall 4.84 m long and 3.1 m high.
The area of the wall is A=l\times bA=l×b
A_w=4.84\times3.1A
w
=4.84×3.1
A_w=15.004m^2A
w
=15.004m
2
Converting m into cm,
1\ m^2=10000\ cm^21 m
2
=10000 cm
2
A_w=15.004\ m^2=15.004\times 10000=150040\ cm^2A
w
=15.004 m
2
=15.004×10000=150040 cm
2
Rectangular tiles size 22 cm by 10 cm.
The area of the tile is A=l\times bA=l×b
A_t=22\times 10A
t
=22×10
A_t=220\ cm^2A
t
=220 cm
2
Number of tiles used to make a wall is
N=\frac{A_w}{A_t}N=
A
t
A
w
N=\frac{150040}{220}N=
220
150040
N=682N=682
Cost of 1 tile = $1.50
Total cost = 682 × 1.50 = 1023
Therefore, The total cost of the tile is Rs.1023.
