Answer 1

Answer:

Step-by-step explanation:

Area of tiles = 13X7 sq.cm

Area of rectangle(where tile is going to fit) = 520X140 sq.cm

no. of tiles required = (520X140)/(13X7) = 800

Answer 2

Answer:

Step-by-step explanation:

given that,

lenth of the rectangular region = 520 cm

breadth of the rectangular region = 140 cm

finding area of the rectangular region= lenth x breadth

(a) Area of region = 520 cm x 140 cm = 72800 sq.cm

now,

lenth of a tile = 13 cm

breadth of a tile = 7 cm

finding area of a rectangular tile = lenth x breadth

Area of one tile = 13 cm x 7 cm = 91 sq.cm

Number of tiles =Area of region/Area of one tile

=72800/91

= 800

Thus, 800 tiles are required.
