Question

A room 7.2m long and 4.2m wide. Its floor is to be covered with glazed tiles of 3m eavh . of the rate is rupees 25 per litre. find the total cost of tiles.​

Answer 1

first we need to find the area of the room length and breadth given so it is a rectangle

area of the rectangle =2(l+b)

=2(7.2+4.2)

=2 *11.4

=22.8m square

to find total cost we need to multiply area and cost per tiles

=22.8 ✖ 25

=570

so the total cost of the tiles = 570
