Question

A room measures 20 feet by 16 feet. The floor of
this room has to be covered with tiles. All along the
four sides against the walls designer tiles measuring
feet by - feet are used. If these tiles cost *62 each,
find the total cost of tiling the border of the room by
these designer tiles.
​

Answer 1

Solution:

Dimensions of the room:

Length (l) = 20feet

Breadth (b) = 16feet

If floor should be covered all

along the four sides against the wall, then

Number of tiles required = perimeter of the room

= 2(l+b)

= 2(20+16)

= 2×36

= 72 feet

Now ,

It is given that cost of each tile

= Rs 62

cost of 72 tiles = 62×72

= Rs 4464
