Question

a solve this math sum pls it's urgent ​

Answer 1

Answer:

no. of tiles required= area of wall ÷ area of tile

= 400 cm x 300 cm / 12 cm x 10 cm

= 120000 cm^2/ 120 cm^2

= 1000 tiles.

each tile costs 22.50 rs.

total cost = 1000 x 22.50 Rs.

= Rs. 22500

Hope this helped. Good luck!

Answer 2

★Given that,A marble tile measures 12cm×10cm.

☯️To Find: how many tiles will be required to cover a wall of 4m by 3m and the total cost if each tile costs Rs.22.50

$\sf \underline{★According \: to \: the \: question: }$

$\tt \blue{area \: of \: te \: wall : }length \times breadth \\ \\ \tt \blue{area \: of \: te \: wall : }3m \times 4m \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \tt \blue{area \: of \: te \: wall : }12 {m}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \blue{ \boxed{ \orange{ \mathfrak{ \therefore \: area \: of \: the \: wall = 12 {oooocm}^{2} }}}} \\ \\ \\ \tt \pink{area \: of \: a \: tile : } length \times breadth \\ \\ \tt \pink{area \: of \: a \: tile : }12cm \times 10cm \: \: \: \: \: \: \: \: \: \: \\ \\ \tt \pink{area \: of \: a \: tile : }120 {cm}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \blue{ \boxed{ \purple{ \mathfrak{ \therefore \: area \: of \: the \: tile = 12 {ocm}^{2} }}}}$

now, the number of tiles can be fitted:

$⟼120000 \div 120 \ \\ \\ \ ⟼ \cancel \frac{120000}{120} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf = 1000tiles \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\blue{ \boxed{ \pink{ \mathfrak{ \therefore 1000 \: tiles \: can \: be \: fitted \: in \: the \: wall }}}}$

total cost:22.5×1000=Rs.22500

hope this helps.!
