Question

6. Square tiles of side 20 cm are to be laid on the floor of a room 10 m by 4.5 m. How many tiles will
be needed? Find the cost of putting the tiles at 131.40 per tile.
of a rectangular park is 1560 m2 and its breadth is 24 m. Find the length and perimeter​

Answer 1

Answer:

Side of square tile = 20cm = 0.2m

$area \: of \: tile \: = side^{2}$

$= 0.2^{2}$

$= 0.04m ^{2}$

Length of room = 10m

Width of room = 4.5m

Area of room = Length × Width

= 10 × 4.5

= 45m.sq

$number \: of \: tiles \: required \: = \frac{4.5}{0.04}$

Cost of putting tiles at 1 sq.m. = 131.40

Cost of putting tiles at 45 sq.m. = 131.40 ×

45 = Rs. 5913
