Answer 2

Given - Dimensions of kitchen and tiles

Find - Number of tiles needed

Solution - Mohan needs 288 tiles.

Firstly finding the area of the kitchen.

Area of kitchen = length * breadth.

Area of kitchen = 240*120

Area of kitchen = 28,800 cm².

Now finding the area of tiles.

Area of tiles = side²

Area of tiles = 10²

Area of tiles = 100 cm²

Now, to calculate the number of tiles needed, we will simply divide the numbers.

Number of tiles = 28800/100

Number of tiles = 288

Thus, Mohan needs 288 tiles.
