Question

How many tiles will be required to cover my floor whose length is 4 meters and breadth is 3 meters and each tile is a square side of 20 cms?

Answer 1

Given

⭐ length = 4m

⭐ breadth = 3m

⭐ area of each tile = 20cms

To find

⭐ Area of floor = ?

Solution

________________________________

⭐ length of floor = 4m

⭐ breadth of floor = 3m

⭐ Area of floor = ?

☞ As we know that floor is in rectangular shape so,

• Area = length × breadth

☞ Area of floor = l × b

= 4×3

= 12m²

☞ Now convert m into cm

• 12m² = 12 × 10000cm²
• = 1,20,000cm²

☞ Area of square tile = side²

☞ Area of tile = 20 × 20 cm

= 400cm²

________________________________

☞ 400²cm area is covered by 1 tile

☞ so 1 20,000m is covered by $\dfrac{1,20,000}{400}$

☞ so number of tiles are 300
