 Hi and welcome to the session. I am Leha and today I am going to help you with the following question. The question says a flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area 1080 m2? Since the shape of the tile is parallelogram, so before proceeding for its solution let's recall area of a parallelogram that is equal to base into height. This is the key idea for this question. Now let's see its solution. Here we have a tile in the shape of a parallelogram. Now we are given that its base is 24 cm, so this is 24 cm and its height is 10 cm, so here the height is 10 cm. So let us write base of tile is equal to 24 cm and height of tile is 10 cm, so area of tile is equal to base into height and base is 24 cm, so 24 cm into height that is 10 cm. Which is equal to 240 cm2. Now we need to find that how many such tiles are required to cover a floor of area 1080 m2. So first of all let us write area of floor is equal to 1080 m2. Now as we can see that the unit of area of tile is cm2 and the unit of area of floor is m2. So we will change the unit of area of floor that is m2 to cm2 because we want same units. Now we know that 1 m is equal to 100 cm but we want to change m2 to cm2. So here we will have 1 m into 1 m is equal to 100 cm into 100 cm. That means 1 m2 is equal to 10000 cm2. So here to change m2 to cm2 we will multiply 10080 with 10000. So this will be equal to 10080 into 10000 cm2. Which is equal to 1008000 cm2 that is 1008 lakh cm2. Now we need to find number of tiles to cover the floor and that is equal to area of floor divided by area of one tile. Which is equal to area of floor is 10080000 cm2 upon area of one tile that is equal to 240 cm2. So here first of all cm2 and cm2 will get cancelled and there will be no unit as we are finding out the number of tiles. And the number of tiles will not have any unit. So this will be equal to 45000 tiles. Therefore 45000 tiles are required to cover the floor and this is our required answer. With this we finish this session. Hope you must have enjoyed it. Goodbye and take care.
