    Answer:

    Length of the rectangular region = 520cm.

    Breadth of the rectangular region = 140cm.

    Now

    Length and breadth of each tile =13cm&7cm.

    Therefore number of tiles required =

    Area of the region / area of each tile.

    =520×140/13×7=40×20=800.

    Therefore total tiles required =800

    hope it helps you

    Step-by-step explanation:

    length of tiles=13cm.

    breadth of tiles =7cm

    area of tiles =13*7=91cm2

    length of rectangular region =520cm

    breadth of rectangular reagion=140 CM

    area of rectangular region =(140*520)cm=72800cm2
