Question

the floor of a rectangular room measures 16m by 11m the floor has to be tiled with square tiles of length 40 cm find the number of tiles required​

Answer 1

answer

17 60000 divide 1600 is equal to 1100

Step-by-step explanation:

areaarea of floor is equal to 16 multiply 11 is equal to 176 metre square is equal to 176 into 10 mm is equal to 17 60000 CM square area of tiles required to 14 into 40 is equal to 1600 CM square number of tiles is equal to 17 60000 divide 1600 is equal to 1100

Answer 2

$\tt ฏGIVEN:−$

$\tt length \: of \: floor = 4m =400cm$

$\tt breadth\: of \: floor= 3m = 300cm$

$\tt length\: of \: single \: tile= 8cm$

$\tt breadth\: of \: single \: tile= 6cm$

$\tt ฏFIND:-$

$\tt no. \: of \: tiles \: reqire = ?$

$\tt ฏSOLUTION:-$

$\tt area \: of \: floor = 400 \times 30 \\ \tt = 120000 {cm}^{2}$

$\tt area \: of \: each \: tile= 8 \times 6 = 4 {cm}^{2}$

$\tt now \: let \: no. \: of \: tiles = x$

$\tt = > area \: of \:hall= x\times area \: of \: each$

$\tt = > 120000 = x(48)$

$\tt = > x = \frac{ \cancel{ 120000}}{ \cancel{48}} = 2500$

$\boxed{ \tt so \: total \: no. \: of \: tile \: is \boxed{2500}}$
