Question

A floor is 4.5 m long and 3.6 m wide. A 6 cm square tile costs Rs.23.25. What will be the cost to cover the floor with these tiles?​

Answer 1

$\bf\huge\underline{\underline{ Given :- }}$

• length of floor = 4.5 m

• breadth of floor = 3.6 m

• 6 cm² tile costs 23.25 Rs

$\rule{10cm}{0.05cm}$

$\bf\huge\underline{\underline{ To \: Find:- }}$

• Cost to cover floor with tiles

$\bf\huge\underline{\underline{ Answer :- }}$

• Length = 4.5 m

• breadth = 3.6 m

• $\boxed{ \bf\pink{Area = L × B }}$

• $\red{\implies}$ Area = 4.5 × 3.6

• $\red{\implies}$ Area = 16.2 m²

$\rule{10cm}{0.05cm}$

• Cost per 6 cm² tile = 23.25 Rs

• $\boxed{ \bf\pink{1 m² = 10000cm }}$

• 16.2 m² = 162000 cm²

• cost = $\bf\frac{ 162000}{6} × 23.25$

• cost = $\bf 27000 × 23.25$

• cost = 627,750 Rs

Answer 2

Area = 450 × 360 = 162000 cm

Cost = 162000 × 23.25 /6

= 627,750 Rs
